I have an internet friend that figured out she was trans through Azur Lane (so she says at least)

Wah
Don't ask me. I know literally nothing about Azur Lane beyond them being boat girls, it being banned on Era, and the game having a lot of Hololive partnerships.
There is no male/trans characters outside of (probably) the player character (the commander). There is little to none talk about gender issues outside the typical “how I can be more feminine commander” throwaway lines for tomboy characters. At best, I heard that the Anime has some Yuri subtext.
I mean, there is a ton female fans of that game but is the first time I hear someone saying they figured out that they are trans from a waifu gacha franchise. This is not Wandering Son.
That is weird then. I assumed there was an Astolfo-esque character who I know a lot of trans/nb people love. Not gonna tell someone that they're wrong for whatever catalyst they had for figuring things out though.
Doesn't really change the fact that Era really only bans "safe" stuff, regardless of what marginalized groups feel about it, so the "but then people will have to talk about it in EVIL places!" mindset is super hypocritical.
Also another amusing anecdote. Literally the only people I know that like Nekopara are trans. Of course this is only 2 people, so not exactly a big sample size, but yeah.
