So you need maximum energy for then rounds that 1. hit the target at all, and 2. land in the kill zone. 40 or 45.
Any of the service calibers perform "about the same". You get more shots with a 9mm and faster follow up shots. 9MM is WAY better through barriers than 45ACP, so if you have to shoot through a car door or similar, a 9MM is superior to a .45ACP.
I have tons of experience in ballistics, tactics, and firearms and I rate the common service calibers, from best to worst as follows: .357SIG, 9MM, .40, with .45ACP dead last.
Your mileage may vary.
The .357 is definitely the most effective round. I like all of the rounds you mentioned except for the .40. Glock has a semi-auto that will fire .357 rounds.
