What is the up-to-date basic workflow regarding database credentials when you launch a local version of a site that is already operating remotely?

Thoughtful confirmations of the community's understanding welcomed. (As appropriate) I'll happily help kick off documentation. It appears not to be documented clearly elsewhere, though if someone else has seen clear documentation on each point of the workflow and related decisions, please include links in your remarks.
As promised above, I've started working on improving drupal docs. I've opened an issue https://www.drupal.org/project/user_guide/issues/3013725
