I've had some contact with Docusaurus and from my experience the Sphinx and reStructuredText combo is a much better solution to creating a robust, maintainable, cross-linked-to-nth-degree documentation where you actually can "focus on your content".

Bonus points if you prefer to not deal with the JS ecosystem and prefer Python.

The main downside is that while reST is well-suited for extending the syntax actually writing Sphinx extensions is, subjectively, significantly more arcane than writing React components/MDX plugins.
