As an EE (same here) you should know the differences.
Caps have

- different dielectrics, that dictate
- different tolerances
- different temperature drifts
- different kinds of dielectric losses

Also not directly related to dielectric but somewhat affected by it indirectly (dielectric dictates assembly technique, size etc)
- frequency and resonance characteristics
- ripple rating
- ESR/ESL.

some other stuff.

Ceramic caps are naturally low in ESL.
They are also more susceptible to microphonics.

Basically, datasheet is your friend.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
