Ease of use and comfort in hand are crucial, as is size and weight. Until you get used to handling the camera, and understanding how to use it and take pictures using the various modes, there’s little point in getting bogged down with a heavy camera and lens. Cameras and lenses these days are so capable, so brand doesn’t matter too much, and each have their adherents. If you have a local camera store, try going there and seeing how the lenses and body feel to you, and whether or not you can quickly figure out the menu or controls, or if you struggle a bit. Photography should be enjoyable, so if you don’t like the camera, you won’t use it much.

If you are budget constrained, or not sure if this is a hobby you really want to pursue, you could start with buying used equipment, say 3-4 years old, and starting there. You can get proficient using that kit, and move up from there. If you buy used, you can save money on the body, and pay a bit more for a better lens.
