Grapheneos has a wonderful how to install procedure. I did it with a Linux Debian machine. It took several tries to get the bootloader right, part of that was I didn't know what I was looking for. Once your phone has the red triangle in the bootloader of the phone, the installer should recognize it, and the installer was awesome from there.

10 does not have a sim card tray, the 9's do. First post with grapheneos on a new to me 9 I was able to get!
Some apps require google play, like android auto and maps.
I'm using grapheneos with open street maps, so I don't think there would be any problem with that. There is a work around to load some apps that require google play with out a google account. I'm guessing that is what would be affected.
