Desk accessories

Hello, I’m trying to make my desk look clean. I want it to look like those desk setups you admire on TikTok, something like that. For my desk, I want it to be clean, minimalistic, and organized. For Christmas I got multiple Amazon gift cards and I was wondering any accessories I should put or do to my desk, and perhaps my shelf on top. Any ideas? Can be any price. I already have cable management on my cart, basically some racks and some zipties
