There really isn't much to fix on a derailleur cage. The guide and tension pulleys can be replaced, screws can be tightened, but that's about it. Straightening a bent cage is possible, but it's really hard to get the alignment back close enough for the derailleur to work properly. I'd buy a low-end replacement rather than attempting something like that.

A long cage derailleur has a longer arm that can accommodate a wider range of gears, making it suitable for bikes with multiple front chainrings. A short cage derailleur has a shorter arm and is better for bikes with a single front chainring. The choice between the two can impact the bike's gear range and shifting performance.
