I’ve been shopping for the same thing. I can report that Intel N100-based computers currently (February 2024) have issues with Linux WiFi drivers. Not a problem if you’re hardwiring it.
I’d also avoid the really tiny PCs because they use the shortest M.2 drives (2242), which limits capacity and upgradeability. You want one that fits a 2280 M.2 drive. Or a 2.5" SATA drive.
