I would recommend:
My Hero Academia. There are three movies with the show but they are extraneous to the plot and the first movie (Two Heroes) has a slightly different animation style and different writers than the show.
Phineas and Ferb
Spirited Away or Howl’s Moving Castle (Studio Ghibli movies in general are awesome, but these two are my favorites)
SpiderVerse movies (1 and 2)
Star Trek: Lower Decks or Star Trek: Prodigy
