Fossify Gallery and Files are already up on F-Droid!
I've had success with Standard Notes personally. I've just used the basic default server, but I know you can self host it. Best of luck!!
If buying new, I believe you can ask to have the modem removed from the vehicle, which wouldn't allow your car to access the internet. Haven't had the opportunity to try this myself yet, but very much plan on it for whatever vehicle I purchase new in the future.
