For durability, I’d recommend a high-quality polyurethane varnish with added mildew resistance. Brands like Minwax Outdoor Furniture Finish or Thompson’s WaterSeal are trusted for their strength and longevity. If you want something more natural, a tung oil varnish can work well with hardwoods, but it might require more frequent reapplication. Just make sure to follow the manufacturer’s instructions for prep work—sanding and cleaning the surface properly will make a big difference in how long the finish lasts.
