capacitor
High voltage capacitors do not generally have low ESR. The importance of low ESR is that it is critical in low voltage and high current ripple filtering, and a high voltage capacitor will often have no ESR specification at all (there''s other ''dissipation'' or ''Q'' measures used), both because it is unusual for HV supplies to have a tight voltage …

High-voltage capacitor in a low-voltage system
A leaky capacitor has the effect of a large rated capacitor that leaks and keeps the circuit from working properly. In most cases, you can over rate a capacitor and get away with it. If you double the voltage value of the capacitor but keep the supply voltage low you might want to also double the Farad value.

capacitor
Lower ESR is better, although it likely will not matter much. I would pick high quality, name brand capacitors regardless. Better than needed will not hurt if you are unsure. In general lower ESR makes the capacitor better at filtering ripple in a low impedance circuit. It''s not directly related to frequency.
When should I use a low ESR capacitor
When the AC source is low frequency (50 Hz, 60 Hz, 120 Hz...) the capacitors are physically large, and could tolerate high ESR (like, 1 ohm for a 1A supply with a 1000 uF filter capacitor). That''s because a one-amp ripple current only created one watt of heat, and a large (over a square inch of surface area) 1000uF capacitor can shed …

why high voltage capacitors are used in low voltage circuits.
The lowest voltage ones were polystyrene capacitors, where you could get thin films that were rated for 16V, and you could get a capacitor of 10uF 16V that was not much bigger footprint wise than a 0.1uF 250V unit but a lot taller.
How to pick voltage rating for capacitors
Depending on the dielectric, ceramic capacitors derate based on the DC voltage applied. The higher the voltage rating compared to the applied DC voltage, the less they derate. So you will have more effective capacitance with the 20V rated part than the 6.3V rated part. This does not apply to (polymer) tantalums, film caps, or electrolytics.
