I know AVM (i.e. FritzBox) and Devolo make WiFi devices, but both don’t offer access points. I guess you could use a FritzBox, but their design don’t make them suitable to be boltet to the wall of a living room.
I found Mikrotik that are a bit difficult to configure and LevelOne.
Are there any other options?
You could maybe flash mikrotik with openwrt? That way you avoid mikrotiks ui etc. Openwrt doesn’t support wifi6 think
WiFi 6 works fine on OpenWRT, you can check if your specific hardware would be supported here: https://openwrt.org/toh/views/toh_available_16128_ax-wifi
Doesn’t support WiFi 6 on mikrotik you mean? As I’m currently running Openwrt on some bottom-shelf Asus routers and WiFi 6 works just fine.
