I've never flown a Corvette but I do not think you should not have any great fears about hanging around in the AZ CZ when the Interceptors arrive, just be prepared in the normal ways with an escape plan.
Even the Vulture listed in the OP isn't threatened by Interceptors arriving unless it is more than two Cyclops or some mix of higher Interceptors. In fact a full spawn (7) of Scouts in a NHSS 4
can be more dangerous than two Cyclops when RNG comes together just right.
But there isn't any reason to hang about either as destroying Interceptors requires quite a different loadout
and skill set
from Scouts and doing it in an AX CZ probably isn't the best place to start learning. If interested in Interceptor combat I would suggest joining the AXI discord.
The SFN has always worked like that AFAIK, if used during hyperdictions it can produce some interesting results but I think they are most likely bugs.
