I haven't seen any of the disney+ star wars shows. I wouldn't say I'm super knowledgeable about the series at all but I've seen the movies. which shows are worth watching? all of em?
Depending on your level of interest and what kind of shows you like the answer could range from all of them to none of them.
I think the show with the highest quality was Andor but it’s more like a political/espionage thriller set in the Star Wars Universe that connects to the movies. So if you want something like the movies it’s not a good fit.
If you like Westerns and Star Wars then the Mandalorian would seem fun, I would think.
You get some Jedi action in Ahsoka, Obi-Wan, and The Acolyte but I think you may need a real love of Star Wars to really enjoy them.
Boba Fett was a side series to The Mandalorian and I think it’s the worst of the shows overall.
There are animated Lego specials which are goofy and aimed at kids but are good for Star Wars kids around whichever holiday is happened.
There are also a bunch of animated shows that may be some of the better quality shows.

I know that may not be super helpful but honestly, other than Andor and maybe early Mandalorian, the quality has been pretty hit or miss. If you love the Star Wars Universe then just getting more Star Wars is fun but if you aren’t that into Star Wars then I think the majority of shows may feel like a slog.
I love Star Wars so even the ones that objectively aren’t very good I find enjoyable enough so it can be difficult to give recommendations without bias.
