> It would be nice if Typst could be a LaTeX replacement that makes actually layout and designing the document approachable

Those goals fall way out of the scope of LaTeX (and of course of Typst). If you want to have more control and power into a document's design, there's ConTeXt - as a graphic designer I just love it and can't imagine myself replacing it with LaTeX or Typst.

But as you said, if you want to concentrate on writing your text without thinking too much about its design, LaTeX or Typst are great for that.
