It's unsurprising the leading choices are still running 9MM/.38SPL. Both calibers make for relatively 'easy shooting' for both novice and experienced handgunners. Both are popular in small and easily concealed models (although that may make them harder to shoot well, especially under stress).
These sort of threads sometimes remind me of when some of the guys & gals in classes and range quals asked what they ought to carry off-duty, in retirement or for CCW licenses. My answer tended to lean toward whatever they
knew they could shoot better ...
and were willing to actually carry.
Some folks will always choose something that offers them comfort in the way of the 'talisman effect', which mostly means capacity or caliber. Human nature. Nothing wrong with that, as confidence can be a helpful thing ... as long as it's a justified confidence, and not a false sense of confidence.
Many folks simply 'like' a particular make/model of handgun. The reasons may vary, but it still comes down to them liking it for its appearance, heft, feel, etc. Fine, as long as they can use it well, if actually needed.
I frankly told a lot of folks to give careful consideration to WHY they were carrying a handgun as a dedicated defensive weapon in the first place, and then to consider how well they could run their 'favorite' choice under difficult and stressful conditions.
I saw my fair share of folks choose an off-duty, retirement or CCW weapon which they didn't shoot as well as another one they owned ... but they
liked it better. Hey, as long as they could demonstrate a 'sufficient level of competence' to pass a qual course-of-fire, it ultimately wasn't my business. Choosing what I carry - and why - is my business.
