> there's no good and easy option to backup your phone other than iCloud
This is false. You can back it up with Finder (since Catalina) or iTunes on Windows or previous macOS versions. You can even do wireless syncing over your local network.
All of the infrastructure that Apple built out before iCloud still exists. You can sync your photos with the Photos app locally. It’ll one-click import everything and you can have it automatically clear out storage on your phone after the import has completed as well. You can then back up your computer however you want - locally, encrypted with Time Machine is an easy option.
