Help with refreshing Dresser w/ wallpaper

I have a white dresser that I bought from FB Marketplace a few years ago, and I'm looking to give it a new look. After using Google Lens, I found out it's the Kylie dresser from Raymour and Flanigan. Recently, I found a beautiful dark brown side table at a thrift store, and I want to refresh both the dresser and my white Ikea desk to match my room's theme. Since I live in an apartment without outdoor space, I'm considering using peel and stick wallpaper or contact paper on these furniture pieces. I've also heard about gel stains but I'm not sure if they're suitable for an apartment. Has anyone used wallpaper or contact paper on painted wood furniture before? Do I need to sand or prime the furniture first? I also like a cottagecore romantic style but would that be too busy for my small NYC room? Thanks for any advice!
