From what I have read, these can be reset to join the Mesh network wirelessly. I have 3 AirPort Express units that I use for Airplay connection to old audio equipment. If the AirPort Extremes are essentially acting as network hubs, then I should only have to reset them to connect to the Mesh network. Connected to that via Ethernet cable are a Mac Mini, and a Ethernet over power device that allows connection to a NetGear device in a back yard shed. In another room where I will have a Mesh satellite, I have another AirPort Extreme.

Q2 - After configuring the MacBook Pro to the Mesh network, will I run into any issues trying to reconfigure backups?

Q2 - I assume I need to reconfigure network settings on the Apple TV4K to the new Mesh network and it should work.

Q1 - Am I correct that the AirPort Extreme will essentially be acting as a network hub? Do I turn off wifi networking on the AirPort Extreme or set it to the same network name as the Mesh? In the room where I will have Mesh Router and one AirPort Extreme, currently connected via Ethernet cable to the AirPort Extreme are an Apple TV4K and an old Time Capsule in disk mode (Used to back up a MacBook Pro). If I reset my 2 AirPort Extremes, connect them via Ethernet cable and set them to join the new Mesh network (in bridge mode), do the AirPort Extremes essentially become network hubs? I am upgrading to an Eero Pro Wifi6 Mesh Network.
