well you have A LOT of catching up to do........LOL
start with episodes IV, V, and VI (4, 5, and 6) which kick started the franchise. then watch episodes I, II, and III (1,2, and 3).
then watch Star Wars: the Clone Wars. this is the the animated TV series and they also made an animated movie as well. maybe start with the movie first and then watch the series.
after that watch Star Wars: Rebels
then you can watch the Disney+ shows starting with the Mandalorian and then the Book of Boba Fett.
you can skip watching the last 3 movies made.....though i do like Force Awakens very much. the last two are ok....not great....just ok.
