stumped on choosing
Most cameras are really good. You should first decide which subjects interest you the most: Kids? Portraits? Landscapes? Urban candids? The moon?? If you've been using a point and shoot, which focal range have you used the most, or wish you had? Wide angle, closer to the human perspective ("normal") , longer ("telephoto"), close up to flowers, bugs and such ("macro")?
If you're not sure of the subjects or focal ranges you can always get "kit lenses", usually 18-55 and 55-250 or thereabouts for not a lot of money. If there is one focal range you like more you can then hone in on which brand makes the best lenses there, and then decide which camera supports those lenses. There's also the question of where to begin and where to grow later, in terms of lenses.
You should go to a store and try a prime lens so you can see the capabilities in low light and subject isolation, it can be a revelation (it sure was one for me!).
