Why'd I recommend training, and not any particular guns?
Because, if the training is any good, they're going to discuss that issue somewhat. And caliber, supposed knockdown power, over penetration, and the rest. In person, and maybe even with a chance to try a few guns.
I'm a fan of Glocks: they're reliable, simple guns at decent prices. There's damn little to go wrong, and if it does, odds are that a simple tap-rack drill is all that you need. They're very tolerant of abuse and ill care. Unlike Sigs and a lot of others that are rather more picky about being cleaned and cared for regularly. You can also find conversion kits to let you use .22 ammo, if you want.
As to caliber -- there's so much variability when you start getting into different types of rounds (various types of expansion, like Hydra-Shock, hollow point, HST -- that's from Federal's list, and there are plenty of others). We're currently carrying .40 SW, 165 grain Federal HST HP in our duty guns, after we piggybacked on a larger agency's R&D. They changed from 9 mm because they weren't happy with the performance in actual shootings...
But all of that really needs to wait. Get the training. Discuss it with your family. Develop a storage plan. Develop your defense plan, too, and know where the gun fits into it. Then you can go out and get the gun and ammo, and be confident from the moment you bring it into your home.
