With all these lessons completed, your application now only has one caching strategy: tag-based revalidation. It's a good one, but as your application grows, it may not be so one-sided.
Individual pages with slow-moving content and few connections may benefit from long revalidation times and path-based revalidation, as well as content such as terms and conditions, or help pages.
Connected content where many document types are joined together with references will continue to benefit from tag-based revalidation.
When to query the Sanity API or CDN is also situation dependent as well. You should be able to query the CDN most of the time. But in situations where requests are only made infrequently—or demand freshness—querying the API sparingly can still be useful.
