To be honest - I wouldn't worry about gluing anything to the top or sides, if you're going to do drawers or shelves that is plenty of Spanish cedar. Also, I've heard that many glues will have an overpowering smell that will not go away easily.

As for other woods - Spanish cedar is used for the aroma and anti fungal, but also because it deals with the humidity better than most woods because of the characteristics of the wood. How hard or soft a wood is, whether it had open pores, etc all make a difference.

I would stick with SC and just do drawers.
