I use GrapheneOS, even that can't protect you from Google unless you are willing to live 15 years in the past.
Any app beyond the absolute basics uses the (yes, sandboxed) Google Play store. But almost every Google play store app then uses Google Play Services to read your location etc., so you have to give that data to Google's software first if you want any app to work.
To get around it every app (or at least the ones like Lyft/Uber and airline apps that you need to move around) will need to be rewritten to avoid Google Play Services.

Not true.
All that's needed is for open source developers to "re-implement Google’s proprietary Android user space apps and libraries".
In most cases, the apps themselves won't know or care if they are feeding data to Google or not. For those few that do care, you can usually find a suitable replacement that doesn't --- or just use the publisher's good old-fashioned web site (aka banks) with a privacy focused browser like Brave.
