All of this, but underlying it I've come to the conclusion that Markdown isn't a good format for a writing environment beyond just simple prose. There's too much left up to the flavour of it and it's got weaknesses.

I've been experimenting with using Markdown (in Typora) in place of Word, but it (and others I've looked at) have zero support for image positioning or sizing, or a way to have different (pre-defined) styles on different tables.

Which is a shame because I like keeping my documents in plain text, in version control and efficiently read by my LLMs. LyX (https://www.lyx.org/) for LaTeX is the closest to what I'm thinking of that I know of, but maybe something exists for Asciidoc or Typst.
