What has worked well for me on making the shelf and edging flush is to use a flush trim bit on the router table with a high fence that has a gap on the bottom for the edging. Since the plywood is 23/32, if you make the rabbet 3/4 “deep” then that gives you 1/32 to trim off with the router bit. Done right it makes for a perfectly smooth transition.
