My rough impression is that "utilitarianism" is generally taken to mean either hedonistic or preference utilitarianism, but nothing else, and that we should be saying "consequentialism".

My impression is that it doesn't need to be pleasure or preference satisfaction; it can be anything that could be seen as "quality of life" or having one's true "interests" satisfied.

Or if you're just looking for a term to replace "utility", how about "goodness" or "the good"?

Or "value".
