This would be a good choice for C17 from Digikey:
It has high ripple current capacity and very low ESR and ESL for its capacitance and voltage rating.
Lifetime is stated at 4000 hours, but that is at 105 degrees C. At a more realistic ballpark of 40-ish degrees C, you'd be looking at around maybe 200,000 hours according to the datasheet...
