I'd say at least three feet deep for goldfish, four would be better. The pond isn't really going to be big enough to keep koi or orfe properly.
Five by eight feet gives you about 250 imperial gallons per foot of depth (assuming a flat bottom). Figure 30-50 gallons for each adult goldfish, and you won't be overstocked.
A marginal shelf is a good place for plants, but it's also a good place for herons to stand and fish. If you don't want to net the pond or rig other heron deterrents, you should consider making the minimum depth three feet.
