Well uh how about cottagecore? it's a good start.

Maybe prairiecore, fairy grunge and its similar aesthetic. Mori kei, naturecore bloomcore, ocean academia, green academia.

Not all aesthetics are listed in this fandom, so maybe you can make a new one.

And btw you really have a good taste in music, I've never been into these kinds of song but now it sounds so interesting. Thanks for the music inspo haha

I'll help you for some more in the next few hours, tho, just want to take a rest for a while.

If the aesthetics mentioned above still don't match to you, maybe you can attach your moodboard image here or on this fandom's discord server. Or adding specific mood or any keywords that you like, like "soft", "intense" or "winterland".
