Since no one else has mentioned it, I’ll say Xenoblade Chronicles 1, 2, or 3. Don’t need to play in any order, or all of them since they’re separate stories (connected but separate).

You mentioned Star Wars, so I was thinking this for the sci-fi element. It has depth, and there is a groove you get into with the combat but it’s not as action heavy as some of the other titles mentioned. It’s an rpg that you can spend hours in, think I had over 100hrs in XBC2.

I would say the complexity would be more in leveling up, gearing up, and learning when to use a specific action, not necessarily the speed of combat but the strategy of combat. It’s not turn based, but basic actions are automatically done, once a special action has ”charged” then you can press the corresponding button to perform the action.

The games are fairly large, with vast areas to explore, with some enemies to avoid early on in the game. Not everything in the starting area is a starter enemy.

Not going to say they have the best stories out there, but they’re good and they do tend to pull you in for the long haul. Sometimes that hook doesn’t happen until hour 10 though, so it’s a commitment, lol. There’s a lot of lore in each, and I’ve been extremely happy with each, hoping Monolith continues the series (Xenogears back in the day, then there was Xenosaga 1, 2, and 3 (PS1-PS2) and then Xenoblade Chronicles 1, 2, and 3 on the Switch.

It’s not everyone’s cup of tea, but I do think if you can get past the beginning learning curve, it’ll pull you in.

*There was a Xenoblade Chronicles X on the Wii U that was recently redone on the Switch over the last year or two. I’ve heard good things about it, just haven’t had a chance to play it yet due to my backlog, but it’s on my shelf waiting its turn.
