I’m sorry, but choosing an OS solely on the nationality of its developers is just careless and should not be encouraged. You should primarily aim for functionality, privacy and security.

The only OS on your list that meets these requirements is Graphene which remains the only true alternative for Android and IOS on mobile devices. The main drawback is that it only works on Google devices due to their superior hardware. The rest of Android Roms lack severely in terms of security features and in some cases are even worse than simple Android. /e/ OS is one of them. The unlocked bootloader and the delay in security updates substantially reduce the security of your device. Mobile based Linux OS are underdeveloped and do not have access to most apps available on the market. They can be considered an alternative only if you use your phone for its basic features and for emailing.

If you can, get a Pixel and install Graphene on it. If not, degoogle your device as best as you can, use a vpn, a password manager and a private email provider.

EDIT: Here is a useful chart comparing all the Android Roms - https://eylenburg.github.io/android_comparison.htm

If you really want to ditch Android, but you can’t get Graphene then your second best choice would be Calyx.

As someone from the U.S., I was so hesitant to switch to another OS, but damn. With everything that’s going on, I kind of feel that I have to switch over to Graphene OS.

This is insane.
