I’ll offer a minority opinion here. If you are going to paint it – why worry about the edges at all? We put edges on plywood to hide the edge “grain”. The paint will do that, especially if you put on a second coat (maybe 3 coats on the edges). You can sand that edge quite smooth. Another option is MDF. With it you can get a very smooth edge.

You also asked about joinery. On simple boxes like this, my first choice would normally be pocket screws but screws don’t hold very well in plywood (or MDF). I would probably do a simple butt joint and secure it with dowels. The picture below is not of plywood, but you can see the dowels securing the joints. I think dowelling like this would give you a pretty solid joint in plywood (or MDF). FYI – this was one of my “no hardware” projects until the recipients put a metal plaque on it saying “made by Uncle Rich – 2009”
