Personally, I don't care much for CZ. Not sure why, they just never vibed with me. They seem like good guns, nice trigger... just a vibe.
The S&W can be nice, but in my experience, people with a S&W auto either love them or hate them. There really is no middle ground. Too many times have I run across a person wanting to sell a S&W because it was a regrettable purchase. It's a very loyalty-dependant brand, IMHO.
Berettas are nice, but I've never been too fond of the looooooong trigger. If this is going to be a strictly range gun, get the Beretta. They're exceptionally accurate, have a wide sight radius, very comfortable to shoot in single action, and magazines are plentifully inexpensive.
Sigs are my personal favorite. Excellent trigger pull, easy to change to a shorter trigger if you have small hands, abundant supply of magazines for purchase (stick to factory or mecgar, all else is junk), and the natural point of aim is like no other.
I like HK compacts, too, but it's not on your list, and if it was I would say something regarding customer service horror stories. I hear the horror stories about Sig, too, but they're more easily repairable with the flood of spare parts on the market. Brownells in specific. In fact, the only people I really hear say bad things about Sig are dedicated 1911 guys... make your own assumption as to why.
If you decide to go with the Sig, you might try to find a slightly-used or new condition P228. It's the compact version of the P226, still has high capacity, and is a little more balanced. This due to a 1/2 inch of slide difference between the P226 and P228.
