Honestly, if you want “quick unprofessional photos” stick with a smartphone.
Standalone cameras don’t have nearly the processing or automated modes of modern phones. So while bigger sensors and better glass can get you a better image it comes along with needing to know how to use the camera and processing the photos afterwards.
That said if you still want something at a decent price I’d be looking at a used Fuji x100 or Sony rx100.
Maybe if I used my selfie camera more often than never.
