Inkling: Would still be considered a lock obciously
Daisy: Might have been discussed a bit more thanks to Wonder like you said, but honestly I think she would have been slept on and Pauline would have been more discussed
Ridley: Would probably be seen as fairly likely, but the "too big" debate would still hurt him
Simon/Richter: The castlevania anime might help Simon's case a bit, but overall I think he would still be seen as fairly likely. Richter would still shocked everyone
Chrom: Would probably not be discussed at all considering how much time passed since Awakening and we got two new mainline FE games (Three houses and Engage). Of all the newcomers he's probably the one that would not make the cut if Ultimate had happened much later in the Switch era and Byleth would have maybe been in base game.
Dark Samus: Would still be discussed in the context of echo fighters discussion
K. Rool: Assuming he would still be requested, I think speculation would have been mostly the same
Isabelle: Like Inkling, would probably be considered even more of a lock that she was at the time
Ken: Probably not too different
Incineroar: Similar to Chrom, would probably not be discussed at all and would probably never make the cut and his spot would be given to a gen 8 or 9 Pokémon.
Piranha plant: No difference, would shock everyone
Joker: Might be speculated a bit because of the Persona Switch port, but overall would still be seen as very niche in speculation
Hero: Probably not too different
Banjo & Kazooie: Probably not too different, like K. rool assuming fan demand would still be there
Terry: Again, probably not too different I guess, wuld still surprised a lot of people
Byleth: Would probably not be speculate on too much because of Alear, but there still might be a niche that would rather want them (or another Three houses rep) before Engage thanks to Three houses very good reception
Min Min: Would probably be seen as "missing the boat" and not discussed too much
Steve: Not too different, it's still huge but most people would still think that it would be crazy
Sephiroth: Probably not too different again, there's some rumors that Remake will get a Switch 2 port which could have help his case I guess and with Rebirth coming soon too, but I think most people wouldn't predict him too much.
Pyra/Mytha: Would probably missed the boat and we would get Noah and Mio, people wouldn't talk about them too much
Kazuya: Probably similar, would be seen as a possibility for a next Namco Bandai rep, but because of Sakurai's comments on Heihachi in Smash 4 he wouldn't be predict too much
Sora: The same, people would still debate about Disney but he would still be a very request character.
