What to watch before Doomsday???

I’ve watched all the movies and series in the MCUs Phase 1-5 ( excluding any projects with Deadpool or Wolverine) and have never watched any projects with the X men, Fantastic Four or Daredevil. What movies I should watch before the new Fantastic Four movie and before Doomsday? ( is it necessary to watch every X-Men movie?) And what’s the difference between the fantastic 4 movies made in 2005-2007 and the newer one from 2015?
