Dr. Greger has a different take on the data. From https://nutritionfacts.org/video/the-risks-and-benefits-of-s... (transcript and sources cited are below the video)

Concerning the Swedish study: Why would those that run around outside enough to get skin cancer live longer? Maybe it’s because they’re running around outside. More exercise may explain why they live longer. And here in the U.S., more UV exposure was associated with a shorter, not longer, lifespan.

Estimates about vitamin D preventing internal cancers are from intervention studies involving giving people vitamin D supplements (not exposing people to UV rays).
