Depends on the circuit.

What devices you are trying to use.

If there are any precedents in the use of capacitors in similar circuits.

you can always open a component catalog and select a capacitor at random and build a circuit around that.

Cataloges/websites like Farnell/RS etc often have a description of the typical uses for their capacitors.
You need to consider it's application in terms of what it's doing, working voltage, polarity, frequency, value etc. If you are not a circuit designer you probably won't understand these things. They are all determined by the design.
