How long have you been playing and how many hours have you played?
I started around Beyond (2.0) and have almost 3800 hours played.
Once my original save got to the endgame, I spent a lot of time maxing out my money, freighter, bases, etc. and contributing to the glyph exchange subreddits. After a while I stopped playing but would check back in after a major update. I didn't really play again seriously until the expeditions started. It's the game I often go back to when I don't have something else to play.
A lot of people find that civilized space is the thing that gets them to stay engaged in the end game. Helping to contribute to a community, helping new players, opening your own business to provide resources, stuff like that. I, of course, recommend the Galactic Hub as your first consideration for a civilization.
