Don't focus on the equipment. Any dslr, be it mirrorless, full frame, or traditional format, will be more than enough to get started and learn how photography works.
Force yourself to use manual mode and learn how fstops, shutter speed, iso and everything else tie together to make an image. I know you said no refurbished, but the used market is ideal for beginners. I went to school for photography (not my current career) but I still use a 20 year old nikon with the kit lens and a couple nice prime lenses I added along the way. The equipment rarely holds you back. With that said, once you have your feet wet, lenses are where you want to invest. An entry level camera with a nice lens will take better pics than a high end camera and shitty lens.
