>>4185002at the end of the day, you just gotta look at some samples online and pick the camera that takes pictures that you like. then you gotta consider if the camera is something you would want to hold and shoot with, then you gotta consider if it has lenses you like. you dont have to worry about anything else. i have some full frames but if i could only keep one camera it would be my em1 ii.
if you havent used it before, try wikimedia commons, searching via "Photographs by camera manufacturer"
https://commons.wikimedia.org/wiki/Category:Photographs_by_camera_manufacturer its a useful resource for comparing pictures from cameras that aren't really art, just pictures of stuff. makes comparing quality fairly easy as theyre typically unedited too.
