@the OP:
As worded, I have difficulty with what you are looking for in your survey. With your narrative, I have a better idea. Please keep in mind, we are all different and have different preferences, that is why Baskin Robbins has 31 flavors of ice cream!
For my quirks, I prefer wood and steel over polymer pistols. While I have a number of revolvers, I am very comfortable with the 1911, having relied on one when I did my time in the Army. What works for me may not work for you.
In my carry rotation, I have 5 sidearms, each fitting a specific niche. For example:
If I don't anticipate a problem, and there isn't hostile activity along my route, I will carry either my S&W model 36-6 or my Mauser HSC (380) with Hornady Critical Defense ammo.
If I have one of my gut feelings or there has been hostile activity along my route, I will carry either my S&W model 439 with Hornady Critical Defense ammo or a 1911 (government or Commander) loaded with hardball ammo.
If I am traveling long distance, and I can legally carry en route, I will either shoulder holster a Colt Trooper MKIII or a 45 or my S&W model 439.
Please note, I can only carry out of state, since my state doesn't recognize one's right to self defense.
If you don't have much experience with handguns, I would strongly suggest that you focus on a revolver. While the capability of firing 357s is nice, I wouldn't use a 357 for defense. Remember, you need to be responsible for every round you fire, so firing should be a deliberate act on your part. Therefore, I would suggest that a newbie look at perhaps a S&W Centennial or Bodyguard style revolver until they gain more experience and earned confidence.
With that being said, I feel that I must share this. I have been shooting handguns for close to 40 years. I have shot NRA 2700 precision bullseye matches, PPC matches, metalic silhouette matches, and fun matches involving steel plates and bowling pins. That was all before I became disabled. I now feel the need to carry, since I can't flee threats. I have fired in simulated stress situations, but not since becoming disabled. I plan to start shooting IDPA type matches in order to learn what I can do with respect to my disabilities. You need to anticipate what you may encounter, and how you would address the threat. There is a 50-50 chance that if I have to engage a threat, it would be while I am defending my 2 young children; therefore, job one is to cover their escape to safety.
Revolvers that I would suggest that you might consider would include:
A Chief's Special (model 36, 37, or 60) - 5 shot - J frame
A M&P with 3 or 4" barrel (model 10, 13, 65) - 6 shot - K frame
