Tutorial, Blog post or Webinar about DatoCMS Good practices

Hi, as DatoCMS Partners, it would be great to have access to Good Practices Guide from DatoCMS on how to use Preview/Publish, Listen query, Subscribe query, GraphQL query cost, Staging vs Production development on big projects. I’m already aware of all the solutions, but I want to know how to use them the most effective way in a project, so that Staging/Production/Other environment, have different/same content based on different context.

Thanks
