I've talked to a couple LEOs about this and they said 357 and 44 don't use for home defense because they're more likely to go thru the walls along with hitting the perp and to use 40 or 45 hp, that it's the safest

This seems to make sense for the 357 or 44mag. You would not to put your good neighbors in any danger. Unless you are sure to hit your mark.

Hmm, Let me recall.....

When I shot Hornady 357 and 44 mag JHP's into drywall the cavities just filled up with Gypsum. They only barely started to expand.

With all the calibers you listed, it's a fair bet that even if the projectile did fully expand, it would still penetrate two sheets of drywall and enter the next room with enough energy to kill someone.
