The physics are pretty straightforward regarding the terminal ballistics of various rounds. Obviously, the larger, and heavier, and faster a bullet is, the more energy it has available at impact.

How this energy translates to 'stopping power' is less clear cut. No two people are built the same, and there are examples where a .22 into the arm can 'stop' some people, while 4 or 5 rounds to the chest from a .45 might not be enough to 'stop' someone else (at least in time for it to matter.)

Use as big and as fast a round as you are comfortable using. A fast 9mm round may carry as much energy as a slower but heavier .45 round, but unless you hit something, it won't matter.

Personally, I like the 9mm CorBon +P 115gr JHP. Either that or a firm tone of voice will stop most people.

115gr JHP

Please forgive my possible ignorance, but I gather that JHP is a brand of ammunition, in which each round has 115 grains (?) of gunpowder? Is 115 grains considered much, or little, or in-between? Thanks.
