Haven't read all the other posts but it really comes down to preference. I absolutely love the M&P Shield Plus both in how easy it carries and how well it shoots and that would be my first choice. I rented a Sig P365 and although definitely smaller, I did not prefer the feel of the gun. Others love it.
I had a Glock 19 and it printed quite a bit for me due to the blocky shape. It was odd that even though the Walther PPQ is a bigger gun, it didn't print as much on me because of the shape. However, everyone's body is different and some carry the Glock 19 really well. It was a great gun to shoot and I would always recommend anyone to take a hard look at it as an option. I personally prefer some kind of safety mechanism and would not want to carry a Glock without a Striker Control Device. Others are fine with doing so. Again it is preference.
Really it is going to come down to striker vs hammer, carry capacity, size, price, etc.
One of the biggest lessons I have learned is a gun can look great on paper but be a completely different animal when shooting it. Narrow the options and do whatever you can to shoot those before deciding. If you can't, try to buy used and if you don't like the gun, you probably won't lose much on reselling.
My preferred order:
M&P Shield Plus
M&P 2.0 Compact/Glock 19 with SCD
Sig P365
Glock 26 with SCD
Glock 43X with SCD
Glock 43 with SCD
Prioritizing a balance of size and capacity. No experience or opinion on the CZ options.
