If you buy a used DSLR/Mirrorless camera, ask for the shutter count. If the seller does not know or will not check, look for a camera with known shutter count data (or ask for an average). IF YOU BUY YOUR CAMERA USED, IT IS VERY LIKELY THE INCLUDED BATTERY IS "CONSUMED".

Mirrorless cameras with a high shutter count are likely fine (most have ~200-250k mech shutters) but should be discounted to match.

Smartphone: The camera you already have. For the most part, many have cameras which are good enough (or are "P&S quality"). While not as good as a Mirrorless or DSLR camera, image quality is generally good enough.

Mirrorless: These are similar to DSLRs but have fewer moving parts and smaller bodies. These use the same sensors as DSLR cameras, but have different lens mounts. In most cases, older SLR lenses can be used with an adapter (Sony LA-EA, Canon RF>EF, Nikon F>Z).

DSLR: Similar to Mirrorless cameras, but use different lenses and have larger bodies. These still get better battery life compared to mirrorless cameras. It is not uncommon for lenses to be cheaper due to the used market. NOTE: I am showing a prosumer DSLR, but it is not required.

Point and Shoot: Due to smartphone camera advancements, these have become less common but are still worth considering. Due to smartphones being “good enough” today, MOST P&S cameras have been discontinued. You are (generally) better off with a used high-end P&S these days.
