Monoprice make a HDMI switch that does a lot of this. No metadata for game mode, etc. as far as I know but I have:

TV

Apple TV on earc connection (HomePods for sound)

Blackbird switch with all other devices.

It can automatically switch between everything, but also has an IR remote for selecting an input.

I've had bad experiences in the past with autodetecting switches, especially that tiny square one. But I should give this a shot— it would be awfully nice to just pipe everything directly to the TV and have the AVR in eARC-only mode.
