Short summary:
Maybe a fair phone? https://shop.fairphone.com/fairphone-5
Me and my 6700K/GTX970 machine.
Works like this for me:
Tap password field
Bitwarden pops up requesting fingerprint to unlock
Select the credentials you want to use
Autofill
Not quite sure what you mean by fully unlocked here. I don’t see the problem with all credentials being unlocked if you have to unlock on every access to the db.
The first one you listed is an ISO standard date format, and is the only way to go :)
