I want to see main character either coming out, or at least coming into terms with their sexual orientation.
The whole point is to find example that mimics "real life".
Okay, that's a bit clearer. Though I'm still not sure if you're looking for outright lesbians, or simply "I like girls", since you mention Yuzu as pansexual.
https://dynasty-scans.com/series/making_progress_on_yuri_before_the_deadline IIRC the MC comes out (or is outed) and flees a homophobic home and high school. It's not a huge part of the ongoing series, but it's the initial setup.
Arioto was already mentioned. The MC is defiant but the deuteragonist is very self-aware, and the MC comes around, and a lesbian bar is a major component of the setting.
Whispered Words. The MCs are into cute girls, or into the other MC.
There are a lot of modern titles where WLW just happens. There's not "I'm gay/queer/bi/homosexual", but also not "you're the exceptional girl". I.e. titles where orientation simply isn't an issue. Whisper Me A Love Song, Bloom Into You (I think, though side char Sayaka does have a talk with some adult lesbians). Blue Star On That Day. Room For Two (that one, there is some fear of coming out, but there hasn't been talk of liking girls in general or not.)
I forget what Girl Friends did with all this.
