I also recommend Aurora Store as a complete replacement for the Play store. The one thing is that I've never tried using apps that I paid for on it but it works very well for any free apps. There is an option to use a Google account with Aurora but I've only ever used the anonymous account.
The only slight dowbside is that I haven't figured out how to auto update appd, so your apps will get out of date without you being notified and you have to manually do it. This problem might literally be solved by a simple setting thay I haven't bothered to look for, IDK.
On the plus side it includes all the official play store apps, along side some that aren't allowed by play store.
For examples, Newpipe, the superior replacement YouTube app that isn't allowed on play store due to it subverting advertisements and allowing a few features that are useful for downloading certain things.
