Mine are of course also on a VLan but with no Internet access unless they need it for everyday operation (like a radio, or the amplifier that can play Spotify).
We don’t use the manufacturer apps at all. Everything is integrated into (fully local) home assistant. No need to open a specific app to operate a switch, or a light. Everything in one place. Trivial and incredibly clear. Things that can be are of course automated.
I’ve gone with CachyOS, frankly it just works. Can recommend. You can tinker more if you want to, but there’s no need.
