And instead of powering parts directly, use a boost circuit to suck all the juice out of the cap to make 5V.

With that much capacitance (100F?), you should use an external supply.

And then hook the 5V regulated line to an Arduino input pin so it can detect when the input power goes away and it's running on the stored power.
