as above.
I was looking at the range available in mouser and I came across a varied selection.

examples:
- some are even supposedly "designed for audio" (Nichicon LKG series)
- some are supposedly designed for switching supplies (CDE SLP series)
- and many many more
What purpose is it for?
If it's first capacitor after the rectifier, rated voltage (be sure, that it's greater than voltage in unloaded case), ripple current and tangent delta are the most important values.

- derating for ripple frequency
- derating for temperature and length of life
- ac voltage and dc voltage rating at frequency vs dc and ripple.
Inductance, ESR.. etc shrug
Determine the minimum specs you need first. Then derate the voltage and temperature if possible for longer life.
Also the capacitor just after the rectifier should have adequate ripple current, derated if possible.
Some linear voltage regulators may have problems with output capacitors that have very low ESR.
