Nikon D3500 + 18-55mm VR Lens Kit
This is the ideal DSLR beginners kit. The body is well spec'd to allow you to learn the basics of photography. Yes that means taking the camera off "P" although it works pretty well on P mode. Put the camera into TV (time value) mode for sporting shots or AV (aperture) mode for your model shots or as you wish. Youtube will be your friend as you learn the best mode and style for your desired outcome.
You could also consider an inexpensive 50mm portrait style lens to add to your kit with an aperture of f/1.8 and learn about Depth of Field and capture those soft focused areas. Get creative with your new Nikon D3500 18-55mm lens kit.
