No problem, bringing it here was the right step.

I think one reason that this is difficult to answer is that the expected
output is not clearly defined. I wasn't sure which parts are supposed to
be Markdown strings and which should become structured JSON.

Take a look at [pandoc.write], which was added in pandoc 2.17. It
expects whole documents as input, which you can create with
`pandoc.Pandoc`.

You might also find good use for [pandoc.utils.make_sections], a
function to turn a flat document into a more hierarchical structure.
