By reading about the new inclementations on Google I decided to leave from Google services entirely, already stoping using Windows for 6 month and Chrome, but sttil dont sure about a gmail(Some important things are signed in gmail accont) and some services like Youtube and some android telemetry(already rooted)
Skiff is another option to replace Gmail, it has 10 Gb free storage.
For Android check out this website: https://www.privacyguides.org/en/android/#operating-systems
Make sure you don’t depend on features like email clients. You also can’t use encryption like PGP so, that will mean that you’ll only have E2EE if you’re sending to other Skiff users. (There is no external E2EE with Skiff).
