My opinions on fnaf gacha :>

Genders/voices

I know this will likely spark a war but its a topic I haven't mentioned yet.

Personally I don't think the souls or voices = animontronic genders, because a lot of characters would become female. (Including Michael) Nor do I believe in custom modes = gender. So what if a guy entered Ladies/girls night they can attend to. Its not an all girls thing. Besides Foxy would've became a girl too lmao.

Just by voice; Bon Bon, Bidybab, medicores, Toy Bonnie, Funtime Freddy, and Funtime Foxy would become girls.
Funtime Freddy mimics voices that would mean girls too.
Funtime Foxy records and replays parents voices at given times. Though I don't think either have voice synthesizers.

By souls/remnant; Michael, Ennard, Golden Freddy, the funtimes, Lefty, Puppet, Vanny, Mangle all mostly would become girls.

Michael is only alive thanks to the remnant injected into him by the scooper. As the scooper's blueprint (S.C.U.P) showed the ability to inject remnant. It wouldn't surprise me if Mike is containing a fragment of Elizabeth's remnant inside him or even some of the other female dead kids remnant.

Vanny, Mangle and Ballora would mostly become male. Vanny has William living inside her slowly taking over her body. Mangle I believe in being Susie's dog and has a lot of Foxy's remnant inside him. Ballora we don't know who's remnant of the mci kids is inside her. Though its a 3/5 chance its boys 4/7 if you add Evan and Charlie to it.

Personally I find it odd that Puppet and Mangle would be girls despite their counterparts are males. Both Puppet and Mangle's counterparts are referred with only male pronouns.

Puppet even keeps the male pronouns inside the Freddy Files as well.

I don't think the excuse of "Oh but the Nightmares are the darker side of the souls"

If thats the case NIGHTMARE CHICA/JACKO CHICA should be BOYS too.
Why would it only affect one of them?! Why ignore Nightmare Mangle who also is male alongside Nightmarionne.

Honestly where do peeps see she or her mentioned on these three?

I remember when peeps used to think Bonnie was possessed by a girl, Chica was possessed by a male(Chica bully) Funtime Foxy being possessed by vice versa Female soul-male suit Male soul-female suit, Ennard was possessed by Baby's mom, and Ballora was possessed by Baby's friend/or supposedly sister at times.

If we're going to go by what Scott says Spring Bonnie would be female, Springtrap/Scraptrap would be trans, and Funtime Freddy would be a female.
Though I don't think Scott wants us to focus on the characters gender as its not important to the lore. In all honesty animatronics don't really have genders or sexualities as it is they don't express such feelings.
