My current problem in Windows is there’s at least 3 system functions, PowerToys and screensaver places vying for control somewhere that I have to manually turn on the Dark theme on when signing in every morning.

Seems like a self-inflicted problem. You can turn off Light Switch in PowerToys. I don't know what screensaver software you're using, but if it's hijacking the setting maybe consider uninstalling it.
