None of the female options I propose to address this issue would be in just because they're female, and I know that the characters currently in the Fighter's Pass for their own reasons and not because of their gender. My point was to push the ideas of representation through characters that are actually quite beloved by a number of people from games that are equally, if not more beloved. And more specifically, I'm trying to get those in support of female characters to address the diversity issue to rally behind characters that people will have a harder time fighting back against (I mean, the Smash Bubble will always rail against every character that isn't for them, but that's another conversation) and solidify the movement beyond "female" fighter in general to more specific goals to result in change and inclusions in the roster form notable female characters.
Male coded refers to the fact that many of the genres and archetypes you mentioned are primarily dominated by male main characters. There's reason for that given that earlier video games were heavily targeted at the young male middle class population in the US during the 1980s and 1990s, but it's still a reality that males lead a disproportional amount of video games compared to female characters and characters of color (which is in an even worse state than the already lacking female percentage of lead characters). You can have all these really diverse "types of characters," without actually having diverse fighters when it comes to crucial facets of your identity such as race, gender, and sexuality. A great deal of characters have diverse "character traits", but they themselves are not inherently diverse in other areas that can be crucial to your lived experience. Gender will determine a great number of the pressures you face in life and inherently does create a different set of expectations from those born as males through society's gender roles and traditional modes of thinking.
Just wanting a female fighter isn't really an invalid stance to take regarding character desires. The Smash community treats it as such with an alarming frequency because they're determined to keep their ideas of "how characters work and should be included" above all else, but liking a character because they're a strong female character is just as valid as "This characters look cool" or "I like the game they're from." People like characters for all sorts of "seemingly inconsequential and or 'shallow" reasons" (keep in mind I'm not saying any of these things are inherently shallow, I'm just saying they have been perceived as such by some members of the Smash community at different points). You're in no position to tell someone their reason for wanting a character "isn't enough" and nobody here is. You can speculate chances all day, but a person's desire for a character cannot be challenged as its a personal opinion that they have chosen to express and they are incredibly unlikely to change their mind regarding such ideas. There is no "acceptable reason" for wanting a character in Smash. There is just your reason for wanting a character.
As for Overwatch, people do own more than one console these days and the internet gives you access to basically every game you may not personally play. A person can watch hours of Overwatch content on the YouTube app on the Switch if they want without ever actually playing it for example. Smash is kind of massive phenomenon that reaches out to people across almost all of gaming at this point, and can draw people in with character inclusions, particularly as the Switch itself becomes a more attractive option for gamers everywhere and includes more titles. I don't see an argument against people wanting Tracer or possibly getting into Smash through a theoretical Tracer. Smash isn't that niche to where it's impossible to conceive of such a reality happening.
Representation means something because you want to see yourself on the screen and characters that come from your background represented. It doesn't have to be that way for everyone, but there are a number of people who appreciate the fact that they're lived experience is in some way represented by a character on the screen, even if it's just race, gender, or sexuality. Coming from mediums that don't always do the best job at portraying those sorts of things or don't feature them in prominent roles, a playable character can mean a lot to people, or a seen in which women are given a moment of empowerment (such as in Avengers Endgame when all of the woman heroes have their big scene against Thanos) can mean the world to someone who understands the rarity of such moments in much of media and even fiction as a whole. If you don't see it, that's fine, but you can't impose your personal feelings on to others who do see representation as a relevant topic. In the same way that Geno can be a character pick for his fans, a character that is a pick that people rally behind through or because of representation is a pick for them. You may not like them or what they "stand for" or whatever, but they're not for you and that's OK. Look up, "Why representation matters" and read some of the literature on that subject to see how it stands to benefit people and can be a great positive to see themselves or people of their experience realized in entertainment products and society in general.
I mean, Smash is media, so the fact media focuses primarily on hetero-normative white characters is relevant. That's what media has primarily been designed to appeal to. The early days of the film industry entirely promoted such characters, and that trend generally has carried over until fairly recently. As I mentioned earlier, video game companies targeted a young male, middle class audience primarily in the 1980s, 1990s, and even most of the early 2000s and designed characters to primarily appeal to those individuals. Most of the authors across the canonical literary fields were white males that could afford to exclusively write from positions of either nobility or wealth that were not subject to prejudices levied against individuals from different backgrounds that were considered "not real writers" or "low art." Media has made a lot of headway in recent years, but there's still much more progress to be made. Almost all forms of media were initially produced either by or for white male, heterosexual audiences. They've become more open to ideas and specifically, noticed profitability in other areas once you get closer to the modern era... but there's still a disproportionate number of characters that trend towards white males leading things like video games. I mean, look how hard we have to work to come up with a solid list of female lead franchises and titles. Look how much harder than that it is to find lead characters of color in games. And how many of those options also reinforce negative stereotypes or lack the depth of other main characters for this reason or that? Games in particular have focused on a more narrow section of consumers, and thus reflect a focus on hetero-normative white male consumers.
