Okay, I pretty much feel honor bound to try to find you some recs that fit what you are looking for. You mentioned MCU but I don't know any of you other fandoms so I'll just work from what I got. Oh and I should probably say, I'm not big on angst but I'm also really not big on the cloying domestic girlfriends (it is totally a thing, and I hate it). So I do hope at least one of these is to your taste. :)
