Pre-Doomsday Watchlist

I know this question has been asked at least a thousand times before, but mine is slightly more specific. I used to be a big marvel fan several years ago, but really stopped watching after Endgame. Recently, I really want to get back into it leading up to Doomsday. I know there's tons of spinoff shows and movies, but here's what I ask. Whats the best order to watch the essential movies. I'm not too interested in seeing all the shows, though I know Loki is very important, so I'm willing to make a few exceptions. I'm wondering what the simplest list is for me to watch to fully understand who all and what all is going to be in Doomsday. I also know it's not out yet and we can only guess based off trailers, but anything can help.
