Core difference
Cambridge gives important to for personal or relative significance and important for someone/something to do something for a necessary or valuable action.
Style Boundary
The constructions are not interchangeable in every sentence because the complement structure differs; preserve the meaning and grammar of the clause that follows.

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.
