I'm planning to buy some unfinished pine furniture and I live in a humid area. I need advice on what kind of clear coat would work best to protect it from humidity, condensation, and spills. Should I go for a clear coat or is painting a better option?

Since pine is relatively soft, using polyurethane will protect the wood and help maintain its natural appearance while making it more resistant to stains. If you decide on water-based polyurethane, just be aware that it can raise the grain a bit, so lightly misting the surface with water and sanding it with 220 grit paper will smooth it out before applying the poly. If you go with oil-based poly, you can skip that step.
I've had good experiences using milk paint and chalk paint on pine. Another option is oils, which can prevent the wood from darkening over time if you prefer that look. A simple mix of mineral oil and beeswax works well, and it smells nice too! I built a bench for my kids out of pine and after years of use, it developed a unique finish that everyone loves to touch – smooth with a lovely patina!
If you want to maintain the natural color of the pine, I suggest applying several layers of water-based polyurethane or hardwax oil. They both do a great job at protecting the wood while keeping its natural look. If you're leaning towards staining it, use a wood conditioner first, then the stain, followed by a water-based polyurethane for a nice finish. But if you're okay with losing the wood look, just painting it is the easiest route!
