Although we all have opinions, nobody here can do your deciding for you.
There's not a lot of difference in accuracy and dependability among your choices.
The best thing you could possibly do is find a gunshop or shooting range where they rent time on a bunch of different pistols, buy some ammunition, and try your choices out. Buy the one that best fits your own hand and shooting style.
In any case, starting out you probably should avoid traditional-double-action (TDA) triggers. That is, the kind which are double-action for the first shot, and then switch to single-action for all subsequent shots. Straight DA or SA would be better.
Probably you should also avoid the smaller pistols, since it is very difficult to shoot small, lightweight pistols effectively and well.
Don't worry too much about caliber, as long as your choice is at least as powerful as the .38 Special revolver cartridge. Bullet placement trumps caliber, just about every time. All you need to do is learn trigger control and sight alignment.
