Hi,
I would not recommend F-Droid since Its official client app literally targets Android 7.1 (No SECURE app would ever do that), You can read more here: https://privsec.dev/posts/android/f-droid-security-issues/
As for Aurora store, Its like very incomplete, unmaintained and Google can simply stop it from working at any timeāand using the Anonymous login means you'll be downloading apps in account(s) of random strangers, meaning they can track what apps you use. Aurora store also does not support Play feature/asset delivery.
