General maneuverability is the main benefit. The back wheels more closely follow the front wheels, so for situations like a curved drive-through (curbs on both sides) or even just making turns on roads with narrow lanes, it’s easier to not clip the curb (or other vehicles) on the inside of your turn. And at high speeds, you can implement “crab walk” to make lane changes easier. It makes a big difference with towing as well.
Besides parking, what other benefit is there for 4-wheel steering?
