I really like alternatives, but imo AOSP is really secure and private OS. What I need is a AOSP smartphone with frequently OTA updates (like in Pixel's phone), working out of box.

I wouldn't compromise my security by choosing one of this smartphones.

Frankly, good luck with that. I attempted for a few months to do that for my Pixel 3a (which in theory is officially supported). When I followed the official guide to compile android, I found that a LOT of things did not work that I expected it to, including: VoLTE, SMS over LTE, and wifi-calling. The phone was useless on LTE, I had to force it onto 3G for any phone functionality. I also had a weird issue where a new SIM would refuse to work in it, I had to activate a new SIM in a Google Stock android, then it would work in AOSP.

I had to manually search through the Google image to find what libraries existed, manually extract them, add them to my AOSP build, THEN compile. I was only able to do this because others had done much of the grunt work already (i.e. GrapheneOS), but when it was "upgraded" to Android 10, it all changed and all my work went out the window. Now I just use GrapheneOS and accept the comprimises I have to deal with.

Technically, nothing prevents you from installing AOSP on these smartphones. Even better, you can have lifetime updates and verifiable drivers. In practice, GloDroid exists on Pinephone [0], but it's far from usable.
