I ~~am sure~~ hope somebody™ already thought of this. Feel free to advertise your project here.

Somebody should take document type conversion from Pandoc and version control from Git

And build a frontend around it
Well every one already recommended latex or markdown.
I would also recommend typst, it's a modern latex alternative easy to make templates and a markdown like syntax, none of all the backslash keywords that I somehow always forget.
Uhhh typst looks hot, that one I need to give a spin, thanks!
I made a template a while back when I had to make report, since I had a professor that disliked the markdown look of previous ones.
A bit of a learning curve, but once you get the hang of it, you make a few templates and write on them just like markdown with custom alias and whatnot.
Typst is fucking amazing. LaTeX is powerful but just takes too much effort to use for large part of the population to the point that I just can't recommend it to most people outside STEM. Typst is consistent, easier to use, faster, and collaborative. With no nonsensical error messages, broken builds, and technical debt - I can actually recommend it to most.
Speaking of LaTeX, I really recommend LyX. You don't need to know any LaTeX to use it, and the result is always satisfying
