Welcome to the forum.
You need to get to a shop and handle all of these firearms you're considering. It doesn't matter how we like them, if you don't like how they feel. The grip on the G19 will feel the same as the G17. Of those you have listed, the Stoeger Cougar would be my choice. I have one that my girlfriend picked out. It has 1400 flawless rounds through it, and is a great shooter for the money. The weight doesn't matter, and I would prefer a heavier firearm if it isn't to be a carry weapon.(?) Also, the XD9 can be had for about $400 and is a good option as well (yes, I own one).
