A wood window requires regular sealing to protect it in moist climates, but clad wood can solve this problem permanently. Most premium wood windows are clad on the exterior surface eliminating this maintenance. Aluminum on the other hand, is far less thermally efficient and is subject to severe corrosion problems when exposed to sea salts. Salt laden air increases the electric potential in metals causing rust on ferrous metals and oxidation of aluminum. The anodized surface may not be adequate to prevent this. I would recommend clad wood windows or vinyl. Be aware that some vinyl windows contain internal metal parts (reinforcement) that may be damaged by salt air.
You might want to look at other coastal homes and take a close look at the condition of various window materials to see how they hold up after 10 years or so and see what is in common use. Attend open houses on older homes if possible. We had a home near the Pacific beach where fog carried salt-laden air, and never had problems with wood windows.
