How do I decide what capacitor to use in a circuit?
I am using a voltage regulator, and to get cleaner power, the datasheet recommends using a 0.33uF capacitor. However, it doesn''t say what type it wants. Stupidly, I went out and bought a 10 pack of 0.33uF 50V Radial Electrolytic Capacitors.After looking up on this site, I found that the symbol means that it is a unpolarized capitator.

Great selection in Capacitors
Ceiling Fan Capacitors; Motor Start Capacitors; Motor Run Capacitors; Surface Mount Capacitors; Ceramic Disc Capacitors ; Monolithic Ceramic Capacitors
Basic understanding of ceramic capacitor voltage ratings.
Higher voltage rating is always better with ceramic, as long as it doesn''t mean excessively large package size. Non C0G ceramics "work best" near ±0 V bias, the third letter gives you a rough indication how bad it is to stray from 0 V, but it only specifies the temperature behavior. So, anything goes with bias voltage.

surface mount
A short indicates that one or more of the devices on the circuit have failed short - not necessarily the capacitor. The most common failure mechanism for ceramic capacitors to fail short is mechanical stress causing the ceramic layers to crack and internally short out. Unless you dropped the assembly, I doubt the caps are bad.

How do smaller capacitors filter out higher frequencies than …
If practical capacitors were purely capacitive, then indeed, a larger capacitor would do an even better (or at least "as good") job of filtering high frequencies as a smaller value one.. But capacitors are not purely capacitive; ones we can practically build are also unfortunately inductive, and at some frequency the inductive behavior dominates …
