CDN cache invalidation for atomic deploys

You deploy a static site frequently and must avoid users mixing old HTML with new JS. Which practice is safest?
Options
  1. 1Content-hash filenames for assets and immutable cache headers, update HTML references
  2. 2Purging the entire CDN cache on every deploy while keeping asset URLs unversioned
  3. 3Setting a very long max-age on the HTML document so browsers cache it aggressively
  4. 4Serving every static asset directly from the origin with CDN caching fully disabled
