I would definitely give the Mass Effect RPG's a go.
I gave X4 a go but it did feel very old, and after logging out of Star Cit and into X4 you really feel like going backwards - despite X4 having a huge array of mechanisms all in play already. Anyway, the flight model itself put me off, but I persisted and still couldn't stick with it.
No Man's Sky is a different beast. The art direction is very much 1950s-70's sci-fi novel covers, which isn't to everyone's taste. Sure enough, the launch was ballsed up and there was very little to do, but now there is plenty to enjoy - just look at it as an arcade universe exploration game.
You might want to give Squadrons a go if you're looking for dog fighting. Again it's pretty arcadey, but the Star Wars theme is fun and really takes me back to the X-Wing v Tie Fighter days.
Keeping with Star Wars, SW The Old Republic is very much an old-school MMO, so expect lots of kill x number of beasts and return. But there are great story-led missions with an overall narrative arch covering a dozen or so game archetypes (classes) covering both the dark and light side.
Everspace, I would avoid this, a kids arcade game that I really couldn't continue playing, the sequel was worse - in my mind at least.
But I have to say I would save those pennies for Starfield (though it is on Xbox Game pass on PC). I suspect this will be a good, long-term experience. I hope I'm not wrong.
Here's an out of the box idea... there is a board game The Outer Rim, 1-4 players, that is Star Wars themed again. But it is one of my most played (I confess to having a reasonably large collection mostly gained over Covid...). It is essentially a bounty hunter/smuggler RPG action board game that is easy to play, with light to moderately crunchy rules and super replayable.
