The contenders:

  * https://e.foundation/
  * https://grapheneos.org/
  * https://shop.fairphone.com/ (with e/os).  There's a German phone too, the name escapes me at the moment.
  * https://www.pine64.org/pinephone/ (w/myriad of Linux distro choices).
  * https://puri.sm/products/librem-5/ (again w/Linux).
  * Feature phones (Jio, etc, running https://en.wikipedia.org/wiki/KaiOS)

Personally I got a Pixel 4a with the intention of running Graphene, but haven't felt the pressing need to do the install.
