Do you need to open any doors or use a light (not mounted to a weapon). That makes the long gun a little less viable.
The first thing I would grab would always be the closest. If I am awake it is the handgun I have on me, even at home. If I am in bed at night it is likely to be the 870 in the closet.
I do not have an AR. I would like one but certainly do not feel I need one to effectively protect my home and family.
