Good question. A slope is the way you want
to go and I'd make it fairly gradual, just like
in a natural pond. A common problem in
common ponds is mice, birds and even
toads drowning because they can't get out.

Cover works both ways. It provides safety
for the prey as well as hiding places for the
predator. Some critters may not even approach
or use a pond without cover available. I guess
I'd split the difference, plant cover in some
parts and not in others and hope for the best.
