I mostly use apps installed from F-Droid, so I’m not sure how I’ll use the phone, except that it’s sometimes required as a contact method.

I don’t have to do anything. I use GrapheneOS btw.
The problem for all these things is proprietary firmware.
What problem? Firmware for my phone works fine.
The firmware is made by the phone makers, and partly needs to go into the ROM. And if they don’t make it available, you can’t run Linux on them.
For example, on some phones in order to install Sailfish, you need to update Android first. Plus, that firmware is usually proprietary and not available as source code.
It is easily conceivable that smart phones become so locked down that it is not possible to install something else.
