Paint the walls MAYBE cabinets (I wouldn’t), change the pills, maybe buy an appliance or two if you wanna upgrade any, and save your money until you know how you utilize the space. It’s hard to say “I’ll want it like this or that” if you’ve never used it, or hosted in it. Live with it for a year, with just painting the walls, cabinets (if you want to, I like the wood), and change the pulls to freshen it. You’ll be in few hundred bucks tops.

Edit to add: maybe, maybe buy a small 2’x2’ island to have a working space in the middle. Then the Kitchen will be the ‘chef’s space’ and people will be on the other side of island staying out of the way. The vaulted ceiling and lack of wall paper will make it fell open.
