Filevault needed on a MBP 2019 with T2 chip?

So has anyone, consumers or testers/magazine/tech staff done any tests that test all this? Specifically if it does indeed impact speed across the board on different apps etc?

There is no need to even test, since on a T2 Mac the encryption is always on and there is no way to turn it off to see if there is any difference.

I meant FileVault though. The T2 is separate encryption, whereas if go in target mode could get data off the SSD without FileVault?

It does not matter. Encryption is always on and handled by the T2 chip. All FV does is add a password to the login process. After login is is the same encryption and without FV turned on... so no difference.
 
Just tested booting a MacBook Air (Retina, 13-inch, 2020) running macOS 11.3 with FileVault disabled in Target Disk Mode (T2 security settings set with Full Security enabled for Secure Boot and Disallow booting from external media for External Boot) I connected the computer to my MacBook Pro and was prompted for the password to unlock the drive. Thus, enabling FileVault isn't necessary IF you have a Mac with a non-upgradable SSD and you want to prevent data from being taken in the event your computer gets taken.

Ok thanks that’s good. Does that include mine then please? Also daughter got a new M1 MacBook Air so she doesn’t need to either?

Thanks

If you're being prompted for a password to mount the disk you have FileVault enabled.
 
With T2 MBP16,1 and firmware password / activation lock enabled - is there any significant benefit to NOT using iCloud for disk unlock with FileVault?

When you set it up make sure you make a recovery code and print it out and save it somewhere, because if you forget that password your data is going to be locked up.

I keep mine in 1Password, which feels pretty secure to me and which I can get to even if I don't have said slip of paper :)
