Current status for GrapeneOS on Pixel 10 can be found at:

My personal (obviously not official) opinion after consulting my crystal ball is that there is a more than reasonable chance that we'll see GrapheneOS Stable on the released Pixel 10 series phones sometime in October.
IMO, nothing significantly wrong with any of the 8 or 9 series Pixels. I know that's not terribly helpful. But unless there's something specific you're interested in or concerned about I think it's mostly a discussion between you and your wallet.
I'm quite worried that gogole is no longer releasing device trees
