How about Murena Fairphone/Shiftphone with non-rooted /e/OS and locked bootloader?

There are many custom ROMs based on AOSP: GrapheneOS (for security against hacking and confiscation), LineageOS and its descendants /e/OS, iodéOS, and crDroid, etc. CalyxOS is not doing well right now, but it should be back in a few months.
Make sure you can relock the bootloader after installing to protect against attacks through the USB connector.
Murena ships /e/OS preinstalled on the European Fairphone and Shiftphone. Iodé similarly.
Then there's Volla phone which can have Linux (Ubuntu Touch) and and VollaOS (AOSP-based) on the same phone. There are other Linux phones, but nobody recommends them for normal consumers.
Not CalyxOS right now.

I went with /e/OS, and it works well, even bank apps.
But they do: https://murena.com/america
