A papaya must be ready but fresh. Hence a nice looking outside. Free of brown or black spots or signs of inside-fouling.
When you gently press a finger into the fruit - the papaya must be firm but soft. Too hard means ready in a few days - or foul by then. Too soft means may be already foul inside. A little practice will help you to select your best papaya.
