I'm going to echo the same sentiment: pixel phones.
Why would I suggest them?
Multiple reasons.
First and foremost (for me) is GrapheneOS. Pixel phones are of the few if not only (don't have source handy) that allow you to relock the bootloader. From my reading the security chips that pixel phones use are quite robust. Pixels are readily available, and the more people that use them the more support a device typically had. GrapheneOS is enough reason for me, but may not be for everyone.
I have also used LineageOS on my phone as well, but with the recent stuff that went down with Play Integrity Fix, LSposed, and I believe a few more projects aimed at rooted phones, I can't rightfully stick with a rooted custom ROM.
Not only do I like the software support, I would personally say that my Pixel 7 Pro is my favorite android device I have owned.
