The main thing I'd look to do is get it set-up 1x and ditch the front mech. You can probably do this with just the purchase of a new narrow wide for the front, and then look to see if you need a bigger cassette at the back. I ran a 32 x 11-36 for a while fine. Drop it to a 30 chaining if you want better climbing and you'll only miss out on gearing on long straight descents.
Why even bother with that? Just ride the thing :-)
Maybe - I just think of all the things that are different on my bike now, compared to 10 years ago, the 1x is the best bit. It's also the easiest / cheapest / most transferable part of upgrading any bike.
