I used troff to typeset a few papers, because it was relatively familiar from writing man pages and more light weight than LaTeX. And groff is installed on practically every Linux or BSD box.
But I switched to LaTeX because it it more mainstream for this kind of document production workflow, so for instance we have a LaTeX template for official-looking University letters, which would be hard to reproduce using troff. And I also switched from magicpoint http://member.wide.ad.jp/wg/mgp/ to Beamer https://www.overleaf.com/learn/latex/Beamer for presentation slides.
For man pages there is now the OpenBSD mandoc processor https://mandoc.bsd.lv/ which can turn semantic markup in -mdoc format in to fairly nice html and other formats. And though -mdoc is a bit weird it is easy to use, well documented, and powerful. It is so much nicer than the old -man macros!
