I could really see Pauline getting in first over every remaining Mario character solely based on her recent rise in popularity since her return. Getting reeeaallll

vibes from her.
Which sucks, but only for me, I guess.
Y'all are massively sleeping on King Boo as a fighter choice, fwiw
I've commented about it before but... to be very frank about the Mario cast, including King Boo and Pauline - Waluigi is imo a lock to debut in the next game. The fan demand is through the roof at this point after Ultimate, and his popularity exploding is more than enough if it was enough for King K. Rool and Ridley, I feel like Waluigi's absence from Smash is noted even more than these 2, in terms of it being known to even more casual players, like that's outside of the bubble. I don't see how Waluigi misses the roster next time so if there's a Mario character that's getting in first among the remaining, it's absolutely him. What I am trying to say here in regards with Pauline and King Boo and the rest (like Toad, Toadette, Kamek etc.) is that imo, they are 'fighting' for at best the '2nd Mario newcomer' slot. Because if it's just 1 Mario newcomer coming, I don't see how it's not Waluigi. Now, personally I feel like the push for Pauline is smaller than Rosalina's. Rosalina's popularity feels like it was bigger than Pauline's at debut and she's proved to have staying power. Like she's still super popular to this day. Pauline imo has waned a bit in comparison and I don't see how Sakurai finds something interesting with Pauline as he did with Rosalina. So even though she is not impossible (as the 2nd Mario newcomer again), I don't think the Rosalina comparisons are completely valid because I feel like both in terms of popularity and moveset potential Rosalina had a lot more to go off of compared to Pauline. So bottom line with Pauline is that at best she is getting in as the 2nd Mario newcomer in the game behind Waluigi, if she gets in at all.
King Boo I am even less positive about. Much less so, I'm gonna be honest, I really don't see how he came to be so speculated, because imo he's very unlikely. I can't see how an interesting moveset is made out of him or how he's a popular fan demand (yes, he's speculated in some circles online but I mean come on, compared to a lot of characters, what demand is there?), I think that he would just be a very wild choice a la Piranha Plant and I can't see Sakurai choosing him over... a lot of other characters both Mario and non.
