Without having tried typst myself, I would still recommend learning LaTeX, if you’re ever looking to publish in a scientific journal; most journals accept submissions in either Word (which in my mind is a very painful tool to use, especially when it comes to typesetting and equations) or LaTeX. They then typically convert the input to some internal format, but are probably unlikely to add support for new formats.
If you only ever intend to write documents for your own purposes, use whichever format you like the best; I personally use Emacs Org-mode and LaTeX export.
If you like Emacs, Magit is the best thing since sliced butter. Even if you don’t use Emacs, I would claim that Magit is a good enough reason to start doing so.
