Minor note, you forgot battery life. Pinging your location every other minute for traffic and crowd denisty for Google Maps, even using AGPS, isn't cheap.

When you find battery life randomly tanks for a few days, despite not changing anything in your life, it's always Google Play Services that end up being the culprit

Great point! For me that was not a reason to get a phone with GrapheneOS, but definitely a noticeable/welcome side-effect.
