LibreOffice can handle a lot (I don't know if it can do the more fancy font features LaTeX can yet) so the case here would be to stay on the command line. And Markdown, well, its great in that it is simple, but I tend to hit its limitations very quickly for more complex setups - plain markdown won't do anything but the most simple tables, and of course, there is no way to define styles. I would suggest that your use case is probably better suited for something like LaTeX (or Tex, for more direct control), og ngroff/troff if you want speed. Maybe Typist for a more modern take?
