The key is a flush-mount frame and a door that sits completely flat. Cheap ones have visible gaps or cheap plastic that shows every fingerprint. I went with this one because the frame is slim and the door has a nice matte finish that takes paint well. After priming and two coats it basically disappears into the wall: https://www.amazon.com/Access-Panel-Drywall-Plumbing-Durable/dp/B085617TBL?tag=contractorhub-20 Strong magnets keep it closed without any play. Been up for over a year now and still looks sharp. Much better than the wobbly ones from the hardware store.
