OpenResume is a free, open-source, and powerful resume builder that allows anyone to create a modern professional resume in 3 simple steps. For those who have an existing resume, OpenResume also provides a resume parser to help test and confirm its ATS readability.
I just use the Europass CV Builder. Works fine for me, has been for well over a decade now.
Definitely one of the more subtle benefits of the EU: They made a perfectly serviceable resume builder.
(But yeah, a LaTeX template would also just work forever. This stuff is what TeX and its derivatives are great at.)
