Are there any other agreed-upon definitions of "free will" within mainstream Christianity?

I've frequently engaged in discussions about Christianity that have revolved around free will, particularly with regards to predestination (and recently as of writing this question, sinlessness) and the term is one often tossed around without being defined. When pushed for a more precise definition, people will often answer in different ways, giving definitions that contradict each other and thus lead to confusion. Personally, when I use the term I am generally referring to libertarian free will (LFW for short) , which is fairly well defined, and if someone else says that's the definition they're using I can be confident we're on the same page, ie we mean the same thing when we say "free will". Are there any other "forms" of free will like LFW, with a relatively clear objective definition, that are used within Christianity or exclusive to it? The main attribute I'm looking for is (consistent) usage; if there's a very clear definition used solely by the churches in a small village in Finland, or by a handful of scholars, that's still a valid answer but not as helpful as one more widely known.
