Nnobby45 makes a good point. Likes, preferences, platforms, caliber choices, etcetera are developed over time coupled with experience. Because there are so many choices, my starting point is the ergonomics of the firearm. Example: my larger fingers overlap the Glock grooves but don’t have any problem with the Springfield XDm. Example: when I quickly raise a pistol, I find the grip angle will result in the front sight being low, high or close to what I would term my natural “point of aim.” While I can train myself to shoot whatever platform, the learning curve is lessened by picking a pistol which comes up with the closer sight alignment picture for me. The operative part is - FOR ME. After shooting for a few years, you should be able to walk into a store and know what feels “right” for you.
I would recommend a full size stainless steel, steel or alloy range pistol. The .22 is an excellent starter and learning tool to open the way to the larger calibers. You can afford to bang away with a 9mm, but if you go larger, as in 40S&W, .357 or .45ACP, you’ll soon find yourself looking at reloading equipment.
