Trying to buy a camera as a complete beginner. Need budget friendly suggestions.

  • Budget: <350$ (body only) < 120$ for lens
  • Country: USA
  • Condition: USED
  • Type of Camera: Mirrorless or DSLR
  • Intended use: Photography
  • If photography; what style: Portrait, street, maybe astrophotography in future.
  • What features do you absolutely need: as complete beginner I have no Idea
  • What features would be nice to have: WiFi
  • Portability: <= small bag
  • Cameras you're considering: canon eos 650D, 750D, sony A5000, A5100
  • Cameras you already have: NONE
  • Notes: If I buy anything right now I will be stuck with it for a while.

Edit: Just researched on two other cameras. Nikon D7100 and Olympus OM-DE M10. I think amongst the one I have seen so far going for a 650D isnt worth it and maybe the Olympus OM-DE M10 might be the one I should go for.
Edit 2: Olympus OM-DE M1 @ 350$ 24k shutter count IS this good?

Edit 3: Canon EOS R100 @ 350 $
