There’s a few ways to handle this.
If building boxes is the way you want to go, for that many boxes box joints would be time consuming, but would last forever. I’d do a tongue and dado joint though. Since the pieces are 1/4”, you can use a standard sawblade with a 1/8” kerf. A FTG blade like a ripping blade will work great.

Another way is to buy bins. I got all mine from mcfeelys.
