Oh, no no, no offense of any kind taken.
It's just such a HUGE subject, with so many variables with caliber size, type of bullet, type of powder load, etc. Often evolves into Holy War.
Tell ya the truth, my comment started out to be (of those you mentioned) "forget .32 and .380 as a PRIMARY defense round. Most would agree, a few would not.
Also, you left out .38 in your main common rounds that you mentioned....very versatile round especially in +P variant, can be used in .357 gun of course, and many prefer that INSTEAD of .357 in their gun.
For sure, though, if you only need defense around the home, it's difficult to beat a 12 ga. shotgun for awesome stopping power.
As much as I like handguns, I'll grab a shottie for sure if I can. And have, a couple of times in the distant past, though never had to fire it in anger (the sight of it sufficed).
A $325 Remington 870 or equivalent is the best bang for the buck in all of firearms, IMNSHO.
It's just a little much to carry around concealed
