Good news! Unfortunately I’m not sold on having to have a bridge to access their email using Thinderbird, so I’m not subscribing Proton Unlimited “suite”. Also no working Linux client for Proton Drive (rclone’s is unmaintained and not working).

In standard Android yes, but on GrapheneOS has 1 (one) private space per profile.

Eagerly awaiting multiple private spaces so I can move everything to owner profile.

Negative, full-res photos with EXIF is not possible to access with rclone (due to Photos API limitations).

This is likely via silent updates of Google’s Play Services.

I used Facebook on my GOS phone. I thank Meta for refreshing my weariness of big corp.

You’re mostly right – those names sound like overkill. However do note I have been using Bitwarden’s Name Generator (random noun + number) and I’ve evolved the scheme a bit ( it is now always ‘user’ and I keep adding numbers until the generated username is available ).
