an older one you've either already read or is not quite up your alley is Kimi ni Todoke. I'm drawing a blank, I've read only BL or fantasy romance ones on this website I've forgotten the fluffy, normal shoujo ones....
maybe these ones too? :

These are the only ones I can remember....hope you'd like some of them at least ( TT﹏TT )
OOh, this one

I don't really remember if these are school life or not though
I went mostly for shoujo mangas (〜￣△￣)〜
Omg tysm for all these! I have read kimi ni todoke, but the others you provided, I havent! Will check them out. Thank youuuu!!!
Recs pls for some school life shoujo -- like kono oto tomare, pink to habanero, fruits basket. Those with cutie interactions of fml and ml. With or without angst as long as the characters and the plot are good. All the featured titles under shoujo are isekai or fantasy... i dont like them
