Further guidance
Core difference
Cambridge’s learner dictionary explicitly groups free from/of something for absence of something harmful, unwanted, or unpleasant.
Style Boundary
Both forms are valid in that sense; context and established phrasing can guide the choice without turning either preposition into an error.
Sources and evidence
Sources are shown with the role they play in this guide. Historical or style-sensitive claims are kept within the evidence boundary described above.

Agree With vs. Agree On separates directly documented constructions and keeps the distinction narrow rather than turning a context-sensitive pattern into a universal preposition rule.
Angry With vs. Angry About separates directly documented constructions and keeps the distinction narrow rather than turning a context-sensitive pattern into a universal preposition rule.
Appropriate For vs. Appropriate To separates directly documented constructions and keeps the distinction narrow rather than turning a context-sensitive pattern into a universal preposition rule.
Available To vs. Available For separates directly documented constructions and keeps the distinction narrow rather than turning a context-sensitive pattern into a universal preposition rule.
Be Bound To Do vs. Bound For Somewhere separates two distinct Oxford-documented senses. Bound to do/be expresses certainty or likelihood, while bound for + destination describes travel toward a place. The guide keeps those senses separate from legal or duty-bound uses.
Be Elated To Do vs. Elated By Something compares two directly documented complement patterns for “elated.” Oxford evidence supports an infinitival use as well as elated at/by + noun phrase, so the guide explains the construction choice without generalizing from synonyms.
