We have an entire consulting documentation pipeline build on Pandoc. Everything is written in Markdown. It took a good bit of tooling to make our reports easy to write, but that is mostly automation around our industry specific artifacts. Our reports look quite nice IMO.
Itβs all internal, unfortunately. It essentially cobbles together markdown documents into a processing pipeline that ultimately makes a PDF. Pandoc does a lot of the heavy lifting getting it all into Latex before PDFing. We have lots of quality of life features around figures, findings, and all the things you expect in a professional report. We use Python doit, and other things to sequence out markdown fragment assembly. We have plugins for processing tool output into markdown and it will run Python and R files that generate markdown as a part of the processing pipeline so you can programmatically generate any content your heart desires. Just to give an idea of tooling :)
