I don’t think that Pixels (made by Google) are designed to sidestep Android ;). Unfortunately, what you’re asking can’t really be done because of the vast hardware incompatibilities between brands of Android phones and between generations of them.

The best privacy option ironically seems to be GrapheneOS, which runs on Pixels, as alluded to above. You can get older Pixels pretty cheap. They aren’t my favorite phones but I sometimes consider doing that.
