Decide for monospaced text syntax in RST files

There are different ways to get monospaced font in docs:
- `` :code:`stuff` ``
- `` `stuff` ``
- ``` ``stuff`` ```

According to the [some docs](https://docutils.sourceforge.io/docs/user/rst/quickref.html#inline-markup)
- `` `stuff` `` = interpreted text
- ``` ``stuff`` ``` = inline literal

Usually when I want monospaced text in `rst` I go for ``` ``stuff`` ```. Is `` :code:`stuff` `` going to add some additional functionality/highlighting?

Is `` :code:`stuff` `` part of the `rst` syntax or is it specifi to Sphinx?

Start by reviewing the repository's RST documentation and the cited Docutils inline-markup reference. Done means the project has a documented, consistent choice between interpreted text, inline literals, and Sphinx code roles, including whether Sphinx-specific behavior is intended.
