Woo! #Pixel8Pro is here.
I've decided to give it a week with Google's default OS before flashing anything fancy.
I set it up without a Google account and it didn't complain. Rummaging around in the settings and most of the defaults are sensible and privacy preserving.
So far, the only slightly annoying things are:
Order of the navigation buttons (but can't be changed on Grapheme either).
Hardcoded launcher info screen - filled with news / YouTube. Can't be removed.
No rear swipe sensor.
