Why each one matters
Avengers: Endgame
The most recent Avengers movie. Being directed by the same directors, Anthony and Joe Russo, there is guaranteed tie-ins to Avengers: Endgame to Avengers: Doomsday. Of course, be sure to watch Avengers: Infinity War before watching Avengers: Endgame.
The Fantastic Four: First Steps
Having read the comics and the fantastic four movies, one of the most consistent villains of the franchise is Dr. Doom. Since the movie is titled Avengers: Doomsday, there's a extremely high chance that Dr. Doom is the main villain of the movie and naturally, The Fantastic Four: First Steps is the introductory movie and possibly the most relevant protagonists to Avengers: Doomsday. This movie is the MCU's take on the Fantastic Four; skipping this movie would be a disservice.
Spider-Man: Brand New Day
How could you recommend a movie that's not out yet? Well, this is the MCU movie that occurs right before Avengers: Doomsday, so there's a high chance that it has relevance to the MCU movie after it.
