Proud↗ (opens in a new tab)Cambridge University Press · Direct learner-dictionary evidence for proud of + noun/pronoun and proud + to-infinitive.
Cambridge directly records amazed + to-infinitive and amazed at + complement, making it an evidence-safe replacement for the unsupported Satisfied proposal.
Oxford directly records both ashamed + to-infinitive and ashamed of + noun/pronoun. The guide compares those attested structures without inventing an unsupported parallel complement.
Oxford directly documents averse to (doing) something. This is a prepositional to + noun/-ing construction, so a bare infinitive should not be assumed to be an interchangeable complement.
Oxford documents the idiomatic adjective pattern bent on (doing) something for determination. The evidence does not license a parallel bent + to-infinitive complement for that same meaning.
