I think capacitors are some of the most "flavour-some" components we use especially in the audio sections. I agree that electrical specs such as ESR leads to a better performing cap.
Back in the day before the choice of exotic caps we can choose from today, we used to focus on ESR as a value of goodness so focussed on caps for pulse applications such as WIMAs FKP1 series. They also had another point of merit as they were film/foil.
Part of selecting caps can be down to other measureable parameters such as vibration. It is possible to listen to caps outside the electrical domain with a stethoscope at a minimum. I bet that could be moved on with better instrumentation.
Vibration control with winding tension and case retraint/damping can alter how it measures if that's what you're looking for and so can change the distortion/harmonic profile which as you say, can lead to a measure of goodness.
After that, personal taste probably comes in to play; just plain ol' whether you like the sound or not.
