When sizing a capacitor, always choose one with a voltage rating higher than the maximum voltage in your circuit to prevent breakdown and damage. The capacitance value, measured in farads (F), indicates the amount of charge a capacitor can store for a given voltage.
For precise applications, a lower-tolerance capacitor should be chosen since a higher-tolerance capacitor is not appropriate. There are capacitors available with the same capacitance but varying amounts of tolerance. The capacitance value determines the physical size of the capacitor; as the capacitance rises, the size expands.
It depends on the expected lifetime you need. If you are going to have more than tens of thousands of power fail events, then capacitors would assure you of a longer life, useful if it was an unattended situation like a remote island. However a battery would be so much smaller, cheaper and easier to use, that's the way I would go.
As the voltage of capacitors varies considerably with the stored energy, you'll need to store rather more than that figure. Swinging between max voltage and 50% of max voltage allows you to deliver 75% of your stored energy, with a reasonable voltage swing into your SMPS.

As others have said, the fact that the amount of energy being stored in a capacitor is a factor of the voltage squared makes having a bank of capacitors charged up to a high voltage seem appealing, though depending on the voltage level can be difficult to design around.
