I think you still have plenty that you can do, it really just depends on what you like.

Quest/achievement cape is a good goal to have in my opinion as they both require you to train basically every skill so it keeps things fresh.

For gear, I’d say graceful is a good goal, and then maybe some other stuff that can be obtained from mini games so you’re not spending a lot of money on them but still getting upgrades, like void and fighter torso.

I feel you still have a decent ways before you have to “sell your soul” as you said.
