Earlier quoted context omitted.
The only acceptable phone for me has been a Pixel phone, with GrapheneOS installed. I do wish the permission to install/uninstall were separated for something like this (I may be naive). I have everything installed to a work profile in Android (using the Shelter app). I can globally pause all work-profile apps. It's not the best, because when unpaused I'm not getting some notifications. I need to figure that out.
Graphene is not acceptable either, since it requires putting trust in someone who does not exibit enough stability or rationality to justify that kind of trust. I mean it's only the keys to your whole life, no big.
It seems to me that it's no different than running a non-Microsoft/Apple operating system on desktop.
