Configuration Interdependencies for Drupal 8, 9, and 10

Drupal creates a line of separation between what is content and what is configuration. The line is such that content is stored only in the database, whereas configuration is maintained by the configuration management system. While cached to the database for performance reasons, configuration can be thought of primarily living in the sync directory as a series of flat files.

This sounds like a perfectly clear distinction in theory, but there are several times where interdependencies appear between content and configuration. Understanding the key places where these interface can help prevent confusion and "disappearing" settings due to a lack of understanding.
