Remember that what matters is the coding of the flight (AF), not the operator.
This goes for BE as well as A5 and any other airline, ST or not ST.
I'm afraid you are wrong here. For code-shares outside the alliance,
some (but not always all) of the benefits are granted for the elite members of the FFP of the code-share airline, but not for the other FFP of the code-share alliance members.
Let's take the example of a BE-operated MAN-CDG flight purchased under AF code : FB elite+ members will get lounge access in MAN for sure and non-guaranteed (hit and miss) priority check-in and boarding. A DL Skymiles Elite+ member will get nothing. Same for a EY-operated flight booked under AZ code : FB Elite+ will get nothing.
