The biggest advantage I can think of with wood is its natural insulation- a wood boat will tend to be warmer than its FG or metal counterpart. Wood can also demand much more diligence in maintenance, especially in warmer climates.

One construction method to avoid would be fiberglass over wood, unless it's part of the original construction method. Putting 'glass over the wood of an older boat sounds like a good idea; what the 'glass does is seal in any moisture that may be present in the wood.

Fiberglass- light, strong, and easy to work with.
Aluminum- same.
