When I tried "luksFormat", I was prompted for both passphrase and OPAL Admin password.  For the former it is clear, this is the passphrase for LUKS2 itself. However, I never configured OPAL on this drive, thus, it does not have an Admin1  password (and SID) set at all.

Should I enter an empty one then? And if so, what my actual Admin1 password will be after setup is complete?

Cryptsetup does the initial setup automatically provided the device 
report itself as yet uninitialized.

IOW, it should work on SED OPAL devices in both states. Either, you have 
to provide existing Admin1 PIN or you are setting a new one during 
luksFormat command.
