I’d say that in modern English genderless singular “they” is preferable for an unknown / generic person, for a variety of reasons.
Passive voice can sound old-fashioned, stuffy, vaguely like you’re hiding something — though it remains stubbornly common in scientific writing.
This isn’t a recent change, but guides do often lag usage The MLA has approved this singular “they” for decades now, FWIW, and their guide is good to my eyes: https://style.mla.org/using-singular-they/
