F-droid and Aurora OSS https://t.me/AuroraOfficial is what I use after I disconnected from google.
Aurora OSS uses a anonymous client to connect to the google playstore. It's a skin layer that allows you to shop in the google play store without being noticed.
For Upoop, replace it with newpipe. Mail client I use Protonmail. Also install Warden scanner and see what various apps are tracking. This data can then be blocked.
