I haven’t fully read all of them myself yet(i.e. I’m only partway through some of them) but here’s a list of yuri light novels and books I’ve read at least a little bit of that seem worth mentioning split by genre:
Slice of life with eventual slow burn romance: 安達としまむら(I personally really really like this and read the whole thing in about a week but I know some people think it’s way too slow or that one of the two mcs is too insecure or that the other one is too depressed and uncaring)
If you like time loops: 忘れえぬ魔女の物語
Sci-fi horror: 裏世界ピクニック
Isekai: 私の推しは悪役令嬢 and 転生王女と天才令嬢の魔法革命
Also isekai but from a different perspective: 処刑少女の生きる道*
Comedy/harem: わたしが恋人になれるわけないじゃん、ムリムリ! (※ムリじゃなかった!?)*
Whatever this is(kind of surrealistic at least): 少女妄想中
And there’s obviously also the Sayaka spin-off light novels for people who have read Bloom into you since they(in particular the last one) actually give her a decent ending. And there’s also some other books I haven’t read yet but I obviously can’t say anything about those.
*Books I marked with this asterisk thing have noticeably worse prose than the rest
For manga I liked ささやくように恋を唄う, まちカドまぞく was nice (though it’s mainly not about yuri stuff but there’s a literal ton of subtext and it’s still good aside from that too), and… I guess those two are the only ones that stood out enough to immediately come to mind exactly this very moment.
