The academic CV standard with section headings set in a left gutter beside the content — the layout used by Oxford-style and moderncv LaTeX resumes.
This is a single-column design: every section runs the full width of the page, in the order a recruiter reads. That is the structure applicant tracking systems parse most reliably, because there are no side-by-side blocks for the parser to interleave.
It keeps standard section headings and selectable text, so it stays readable to parsers while giving you more visual character than the plain ATS layouts.
