One more time, I"m just curious, all raise their hands that have ear muffs by the bed and intend to use them in the heat of the moment?
Not me, I have a suppressor by the bed. At that point (just talking about sound level here), caliber doesn't really matter.
Personally, if I'm going to use a 9mm on someone in my house, it'll be a pistol, for maneuverability around corners. If I'm going to use a long gun, it'll be a rifle caliber; I want all the advantages I can get.
