However, the OP's main question was about differences in *A award availability with different *A FFPs.
The answer to this question is yes. It has been established that UA MP and US MP limit *A award availability on non-home carriers for their members, while (at least most of) the other *A FFPs don't.
Routing and rebooking rules and restrictions greatly differ from FFP to FFP and should be addressed in the respective FT forum, as that's where the experts are
No discussions of the world, the universe and all the rest contemplated. Just trying to nail down whether, and if so how, results might be different getting an award ticket on C using A's FFP vs B's FFP. (Inventory question has been answered, that they may differ in availability.)
