I know it would be best to have my highest score be on CR or M, but will my high Writing score help at least a little or likely be inconsequential? Primarily interested in LACs, if that matters.
For a good amount of LAC I think having a high writing score looks just as good as CR+M scores. So i think you wil be fine. There are a few though that still only look at writing. Writing is being eliminated next year.
