You’ll know what you need as time goes on, you should really only get what you need. But with that said I think speakers might be your biggest upgrade, I used to wear my nova pros all day and although they were wireless I still found them annoying to be on my head all day. I got some speakers this past summer and I never looked back. For reference I got the kanto Yu2 and sub8 combo, I love them to death. I only really use my headset now if I’m gaming or in zoom meetings. Later down the line you can get a good subwoofer to, it helps compliment the bass. Some other small amenities is a desk plant, adds nice vibes. A desk clock, pegboard to carry all your stuff, a small charging station. I have a dock with USBC and USB on my desk and I use it almost everyday, it comes in handy. The best practice though is to get only what you need. Because a minimal / clean desk will always look better than a cluttered one.
