Looking at DigiKey again there were no PolyStyrene capacitors listed that I saw. There were PolyPropylene ones but looking at "Features" and "Applications" categories they mostly seem to be designed for snubbers, X/Y capacitors, motor caps, etc. and none actually categorized as "precision", "low leakage", or even "high quality audio" etc.

Do Capacitors Have Polarity? Capacitor polarity is how a capacitor is positioned within any given circuit. A polarized capacitor possesses a positive and a negative terminal.

Polypropylene Film Capacitors: These are the go-to for high-performance applications.

If an engineer’s design demands a precision and stable capacitor, she or he will usually turn to NPO-type multi-layer ceramic (MLCC). This old standby is still the best. If you haven’t checked them out recently, you will find that manufacturers have been able to reduce their case size and extend their value range considerably.
Although all the different types of capacitors provide capacitance - they are not all equal. Capacitance is not the only critical parameter when selecting a capacitor, and each type of capacitor is used in different applications, so sometimes making the right choice is not an easy task.
Class 1: offers high stability and low losses for resonant circuit applications (NP0, P100, N33, N75, etc.). Class 2: offers high volumetric efficiency for buffer, bypass, and coupling applications (X7R, X5R, Y5V, Z5U, etc.). Class 1 ceramic capacitors offer the highest stability and lowest losses.
Film capacitors can have very high precision capacitor values, which they retain for longer than other capacitor types. They are very reliable with long shelf and service lives, with an aging process that’s generally slower than other types such as electrolytic. They have low ESR and ESL values, therefore very low dissipation factors.
You’ll need small capacitors (to fit in a compact space), have a high enough voltage rating for your circuit, and can handle temperature changes. You might opt for ceramic capacitors for general use and a tantalum capacitor for areas where stable capacitance is critical. One of the most significant trends in capacitor technology is miniaturization.
