So called assault rifles that use a light, low recoiling caliber were developed after the experiences of urban fighting in World War II.

I consider 223 Rem/5.56 NATO and 7.62x39 calibers suitable for indoor use. For outdoors battlefield use we have 308 Win/7.62 NATO.

Modern mechanised troops often have heavier support fire available immediately when requested so their personal weapons do not have to be so powerful. But if you are fighting on foot, you have to carry the firepower yourself: 7.62.

For civilian self defense you probably do not need the power of a heavier caliber. You have to justify shooting a person in self defense and it is has hard to imagine being under such an imminent threat if the target is 100 yards or farther away. Self defense shots would probably be at very close range so a 223 Rem should work fine.
