having the ability to "enthuse for" or "enthuse with"?

https://dictionary.cambridge.org/dictionary/english/enthuse give examples of the two usual uses. One definition coincides with your first use. "He was passionately interested in classical music but failed to enthuse his children (with it)".

Although the verb "to enthuse" is originally a back-formation (see https://en.wikipedia.org/wiki/List_of_English_back-formations) from the noun "enthusiasm", it now behaves as a regular and accepted verb, and there is no need to revert to circumlocutions involving "enthusiasm".
