I just use nextcloud as a target for backups (Aegis, Signal, QkSMS). Apps such as KeePassDX I have load the file via nextcloud. My contacts and calendar go through it as well, photos are just set to auto upload along with a few other directories.
As for the home screen layouts, I just take screenshots once I have it how I like and try to remember to take them again if I change stuff.
It's not a full backup but I'm back up and running fairly quickly (Pixel 5A died on me 3 times in under a one year lifespan per device).
Adding to this, automatic plate flippers exist and are pretty popular for show cars to display something else when parked. Typically wired to ignition so it shows your plate only when the cars running.
Issue is if you street park dependent on the state, if the vehicle registration is hidden by the plate being flipped they can likely tow it. Would work great for at work/in your driveway though. Could maybe just have a bypass switch for if you need to park somewhere and display the plate.
Still a pain in the ass that it's this bad though.
