I wanted to verify if the two definitions for the feature(s) designated as datum A in the picture below are equivalent

Yes, they are. In the ASME Y14.5-2018 standard, this pertains to paragraph 5.8.3 and 5.8.4.

They are, but only in this special case of 0@MMC.

Just curious: do you still need 2X when CF is used?
I don't think so.....

greenimi, you don't. The goal is to communicate that it's treated as a single feature.
