I understand why photographers use auto exposure bracketing for HDR or difficult lighting, but what is flash exposure bracketing for? In what situations would FEB be a good idea, and why would you use it instead of just taking one flash shot?

You seem to have lost track of the original reason for AEB: To be sure you nailed the exposure. In this case you use small increments (up to 1 EV at most) while for HDR you would use larger steps (at least 3 stops but 5 is good with modern cameras).
For FEB, it is the same: To be sure you nailed the flash exposure.

Flash exposure bracketing is mainly for the same reason as normal exposure bracketing: to make sure you get at least one frame with the exposure you want.
With FEB, the camera varies the flash output slightly across a series of shots. This is useful when you are unsure whether the flash exposure is exactly right and want a small safety margin without manually adjusting settings between frames.
Unlike HDR-style bracketing, which often uses much larger exposure differences to capture a wide tonal range, FEB is typically done in small steps—just enough to help you "nail" the flash exposure. So the main use case is uncertainty about flash power or flash metering accuracy, not creating an HDR-style composite.
