re: I’ve never seen any Star Wars films. Do I watch in order?

If you want to do chronological order, I THINK it's this

Phantom Menace
Attack of the Clones
*Clone Wars series*
Revenge of the Sith
Solo
**fan movie- Vader Episode 1**
Rogue One
Star Wars (A New Hope)
Empire Strikes Back
Return of the Jedi
Force Awakens
The Last Jedi

Honestly though, I think that's a waste of time.

Go find Harmy's Despecialized versions of the original trilogy (those are the closest thing you'd get to the actual films we saw in the theater).
The effects might be dated, but they're practical, not CGI- they made ILM's reputation with that.
And those are the films that inspired people to love the story.

All the rest- the prequels, sequels, spinoffs- those are just the studio cashing in on the good will spawned by those first 3. If they don't do anything for you, the others won't either.
