In my opinion, LaTeX is useful for typesetting (1) unwieldy documents (2) using as a template for documents you write often and scripting it.
(1) By unwieldy I mean a book or academic writing. Typesetting a thesis or a book is "easy" to do with LaTeX, especially if that document contains a lot of acronyms, glossaries, figures, cross-references, bibliography, etc... there are lots of great templates out there for theses and books; creating one from scratch is more often than not, overkill.
(2) One use case of what I mean here is document generation, say you have a table of employee names, phone numbers, email addresses. You can easily generate new business cards for all of your employees for the printers by creating a script to do so. Though, the initial investment may only be worth it for a larger amount of data.
A resume is mostly about design and is not altered with the frequency that would make typesetting in LaTeX interesting for anything other than curiosity.
Also, moderncv produces enormous files. I agree that LaTeX is not suited to every task.
