Font choice
"The validity of all advice changes with time."
It does indeed. For example, people mindlessly repeat that sans-serif fonts are more readable for on-screen text...supposedly proven by a "test" or "study" (which, however, is never identified with a footnote). That recommendation dates from the time when monitor resolution could not properly render serif fonts like Times New Roman.
Incidentally, just my opinion: If your resume "stands out" because of your font choice, you're doing something wrong.
