So, would a static fire require that the strongback + crew accessway be pulled back from the stack before the fire?

I think it would be a major error if they fail to retract the crew arm.

Pad abort is definitely a no-go with the access arm extended.
Separate question:From memory, for all recent Falcon launches, the strongback is retracted at T-4:00.For Crew Dragon, including DM-1, will the strongback be retracted before fueling, at T-35:00 so that the capsule has a clear escape path?Particularly if the umbilical retractors are designed to work from the retracted position, it seems logical that it be retracted any time the LAS is primed to pull the capsule away from a dangerous situation."Dangerous situations" includes failures during fueling.
LOX loading has started
Venting!
Strongback should start to retract soon.
