Cedar VS Spruce is largely a matter of tone preference;
First off, whichever wood you select, a solid, pressure-tested top is highly recommended for best performance ... you'll be glad you spent the extra. A laminated top (and/or sides) will greatly reduce the tone, detail, and volume of the instrument. The glued layers of a laminated top increase its overall density, and it simply doesn't resonate as well.
I have two Cedar tops (LaPatrie "Concert", Norman ST40). Both have a soft, gentle tone, with lots of warmth but not as big on volume or low end. As someone has mentioned, Cedar lends itself well to finger-picking, which is why most classical guitars use it. My Larrivee D-03 on the other hand is a Sitka Spruce top, and has more volume with much more fullness of tone and low-end punch.
For durability, Cedar is indeed softer than Spruce so requires care, and because it's more porous it reacts quicker to humidity changes.
I sincerely hope some of this is useful.
