I'm a big fan of options too, and letting the organization determine how
important control of a particular setting should be.

Microsoft has a number of Group Policy settings with five values relating to
a boolean parameter: Unset, which lets the documented default chain of
priorities determine the eventual setting of that parameter, plus something
like the above four values that could allow the organization to determine
whether the user is allowed to set a different value.

If the user setting should be temporary (user cannot save this setting) and
the Policy setting always imposed on program load or restart, then two
additional values are needed for a total of seven.

For a string value, perhaps a prefix character would serve:
 "https://example.org/" = default, user can change
 "!https://example.org/" = fixed, user cannot change
 "*https://example.org/" = default, user can change, reset on restart

Or are there wheels with fewer corners already in use?
