sad, was thinking to switch from iPhone to pixel 10 in few months once released exactly for the reason that is clean android and gives and escape hatch to use grapheneOS or lineageOS or calysOS. Any other android phone manufacturer that is supported by any of those projects? Most devices supported except pixel devices are few years old.

GrapheneOS only supports Pixels due to their having superior security features [0]. Calyx supports Pixels as well as some newer Motos and the Fairphone 4 and 5 [1]. Lineage supports tons of devices [2].
LineageOS is the only one of the three that supports older hardware, but I'd recommend getting a previous-gen Pixel for the seven-year (at least) support cycle.
