I think she needs to try many of the weapons listed in this thread in order to make her own informed decision.
I think a shotgun with #4 buckshot or bigger is a reasonable choice for hunkering down and waiting for help, but my wife hates the noise, weight, and recoil.
Bear spray for bears in the woods is likely OK, but using it in your house is not.
I would not rule out a 9 mm pistol or carbine. An AR carbine is also worth a look.
Let her choose what she is most comfortable with, after using them all. Good luck.
