You're doing more in depth setup than I am on my ATEM Mini Pro, so I'm not sure if this helps. But you can give this a try.
Within the ATEM switcher control, on the top left will be a dropdown menu for Files, etc. Just below halfway down is the option to Save Startup State or very similar. I will click that save startup state to create a default startup state. On mine, this saves and then loads which of my cameras is in preview, has my Livestream splash screen as live, audio settings, etc., on every startup.
Quite literally, when you click save startup state, whatever is active on the ATEM when you click it should be what the ATEM starts to the next power on.
