As others have said above, limit your upgrades to seat, pedals, and tires. Go tubeless if you can. Ride the snot out of this bike and have fun. I don't think going with lighter weight components is all that important on a gravel bike unless you're racing. Also, upgrading components on a lower-cost bike can get expensive and you might be better served saving your money for a new bike and keeping this as a backup or bad-weather bike.
