At my university it is some disciplines such as physicist that insist on using LaTex, unfortunately. Word is the de facto standard in cross disciplinary collaborations and in corporate so learn to use that instead of LaTex.
I agree that for collaborative work, the document of reference is most often written in .docx . However, the original question pertained to the ergonomics of academic writing, that are definitely simplified once the simple synthax of LaTeX is learned.
To note that exporting to other file formats is trivial.
Overleaf is a great way to experiment and solves the collaborative hassle.
