I bet supply house is more likely to have HCF cable, which the sheath would be acceptable for EGC plus a green conductor inside then they are to have that product on hand.Forgot example link:

Metal raceway is suitable EGC, flex however has limitations.That is probably true. I have never used MC for IG applications. It's been many years since I have installed IG's. We used to run EMT or flex with 2 EGC's if fishing down walls.

I'm sticking with what I said, you did point out some of the limitations on the flex though.Not really is pulling 2 EGC's. 1 for standard EGC if flex is over 6' or circuit is over 20 amps and 2nd EGC for IG.
