Nikon D3500 or Canon EOS Rebel. both have interchangeable lenses and are intermediate level cameras that come as kits with an additional lens. EOS can be more pricey on a really good starter package, but it is made to get you going. Both integrate with other company's lenses.
Photoshop is standard, however, Faceapp (heavier Snapchat) is a good lightweight tablet photo editor.
If you want a point-shoot you can work photo editing into while taking pictures, I have a Samsung Galaxy 2 which has the software installed on the camera standard and does up to 4K as well.
The Nikon and Canon are about 500USD each, 900USD package, the Samsung was 350ish USD.
The difference between the d80 and d3500 is the CMOS sensor of which the d3500 compresses a little better and the d80 is sharper in between light and dark, if I remember correctly.
