Honestly just watch the movies in order by release date. You can definitely skip Solo and Episode 7, 8, 9. The sequels aren't worth wasting your time on. Clone Wars is good, but it takes a while for it to pick up and it's a children show. Mandolarian is alright, Andor is amazing. At the end of the day, this is a movie series that children can watch so don't expect anything to crazy. Still, amazing characters, storylines, arcs, plot, art, soundtrack. My favorite franchise after Spider-Man, hope you enjoy boss.
