Carport0593 Also, what would be the best way to install these app that I use most frequently:
If you're planning to use Sandboxed Google Play, you can use Play Store for all of the apps you listed (provided that they're on Play Store) except for Netflix.
Netflix's Play Store listing is marked as requiring a Google certified Android OS to download the app, when actually using the app does not.
To get around that, you can use Aurora Store, which is a Play Store frontend which supplies you with its own accounts instead of you needing to log in with your own.
It's important to note that if you want to use Sandboxed Google Play (which you will need for the Proton Mail app to give you notifications, for example), you'll need to have Play Store installed even if you use the Aurora Store. You don't have to actually login to the Play Store, but having it installed is required for Sandboxed Google Play to work properly.
If you have any further questions, please let us know!
