As far as the long gun, I think shotgun or 223 rifle are best for minimizing penetration. With the shotgun, you can select smaller buckshot which should penetrate less.
For me, I use a Zastava N-PAP AK. I have a rail mounted light and a magazine loaded with Winchester PDX defender ammo. I expect it to reliably expand and not act like FMJ. For short range accuracy it is more than adequate.
In all honesty, I think Bullet/Cartridge Selection is more important than caliber/gauge. Select a bullet type that has good soft tissue performance, but not designed to penetrate obstacles as much. A lot of police/military ammo is designed to penetrate light obstacles and still work. I think simple soft point hunting ammo might be better than law enforcement stuff if penetration is driving your decision. That applies to rifle or shotgun ammo. I am not sure where Win PDX ammo fits in that.
On the guns, your list has some pretty expensive selections. Reliability is key. You don't need an expensive battle rifle, just a good gun you trust. Preferably one that can mount a light and maybe a laser. A $400 defense shotgun will work. So will a $600 AK. So will a much less expensive AR. Whatever you get, put some rounds through it at the range and make sure it runs without any issues and handles the ammo you select.
Hmm never thought about using my npap...doesn't get much use because the stock kills me but if I buy a stock folding adapter it might get some use hmmmmm
