There a wood shop in town here that serves woodcrafters and specialty cabinet makers, that will cut, bead, and cove strips of whatever (cedar). REALLY helps with the labor time and limits waste. Also allows people with limited shop tools to build a bangup wood strip.
If you're going the easy way, stitch and glue with thin plywood/epoxy is quick. The differences in the ply's are wood type, glue type, and gaps between the layers that will trap air and rot in the cheap stuff. Having said that, there are boats still being paddled built with cheapo ply that are almost 15 years old that I know of.
I would decide where you will paddle the most. Then what design you like that'll fit the app. Then what construction method will build the boat the best within your budget. Once you have those parameters, you'll get much more specific answers to any questions. Or start with design questions for where you want to paddle.
Hope I didn't assume too much and got too basic.
