I have a brand new TV where if I plug the HDMI into my M4 MBP, MacOS ceases to have any functioning WiFi capability. Unplug the HDMI and internet returns instantly.

That's probably because your TV has support for Ethernet over HDMI enabled. Run ifconfig to check if there's a new (and, possibly, default-routed) interface when you plug that TV in.
