Interior Wall Paint & Bedroom Carpet

I’m refreshing my home and need two things handled in one go. First, all interior walls require a clean, even coat of paint. I haven’t locked in a finish yet, so I’m happy to hear whether a matte, semi-gloss, or even a glossier option would work best for long-term durability and easy cleaning...
