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.
