Late to this thread, but as I've pointed out in previous ones regarding loads, lasers, and barrel lengths, there just is no "best" answer. It's got to be dependent on your home, and the "most likely" threat you will encounter there.
If you live in the boons, and might have an encounter outside your home, a heavier load is probable best for you. If you live in a condo where the longest shot is 7yds, #6 is fine, and #00 is borderline reckless.
For myself, the shotgun is "usually" in the bedroom, and if I need it, I imagine that upwards of 90% of probably encounters would include covering the bedroom door, or the hallway immediately outside of it. because none of these ranges exceed 10yds, #4 is my load of choice. Should a situation present itself (highly unlikely) that this loading is not sufficient, it certainly allows me to fight my way to a heavier weapon if need be.
Realistically, few if any of us will ever encounter an invader in our homes. Of those who do, only a tiny fraction will encounter well armed, and armored invaders in our home. So in the *unlikely* event that I will need to fire my shotgun, #4 is *most likely* to be the safest thing for myself, my wife, and my neighbors.
IMHO, you are best off tailoring your answer to your own "most likely" scenario, rather than someone elses.
