We have a partial port of GrapheneOS to the Pixel 11 series after a week of work on it. We're unable to complete the port due to lack of support for ARM hardware memory tagging in software, firmware and near certainly hardware. It appears Google cut an important security feature to save money.
Simple solution: wait until they announce support before buying a new phone. Short of your current one breaking or no longer updating, you don’t need a new phone right now, you can wait.
If you do need one right now because of one of those reasons, sucks, but just buy the most recent one that is currently supported (the 10) or buy one that will EOL sooner than you’d like (maybe an 8 or 9, used/cheap) while you wait for the new one (the 11).

Hopefully the resale price on the 11 tanks (it won’t) then.
