I haven’t finished this but there’s a series (one fic completed) I can dm you the link if you want much more found family in the second fic iirc but it’s also a time travel fic unfortunately it does have steddie in it and way more eddie than jonathan but that’s the closest to more friendship/found family focused fic I can find in my bookmarks since the st fics I have bookmarked are mostly byler and ronance
