It seems that you can use pandoc-crossref for such case: see the manual here (https://github.com/lierdakil/pandoc-crossref/blob/master/docs/index.md).

To answer the technical part of the question, `pandoc -t native <<< 'See the [Quick introduction].'` shows that "[Quick introduction]" is parsed as a normal string. You can create a span instead by adding a class: [Quick introduction]{.sectionref}. But even then, it will be simplier to parse its content if it is limited to one string (like "Quick-introduction").
