When someone brings that fresh scent of the outdoors back inside with them…what causes that? What is that “fresh scent” and why does it stay on someone?

So smells are just molecules. It’s not just the outdoors but any scent. For plants, they’re called terpenes. Those molecules stick to things and are moved around in the air. When someone comes from the forest and smells like pine or lavender it’s those specific terpenes.
