This is what I do when the edge will be exposed.
I start with a piece of stock approx 2" Square and as long as needed. I then dado a 3/4" rabit on 2 sides where the plywood can butt up against and also provide a good gluing surface. Then I roundover the outside corner. I then use glue and a pin nailer.
