Michigan usage, at least in business and professional circles, indicates that "woman" is preferred, if not "person." There are "chairpersons" of committees, often shortened to "chair." "Lady" is rarely used, except in the introductory phrase, "ladies and gentlemen."

Preferences as to honorifics tend to vary with the professional and social setting; it seems to me that most lawyers, accountants and business managers use "Ms," but that "Mrs" and "Miss" are used by school teachers.

I am happy to report that the use of "Sir" and "Ma'am" have regained acceptance in my circles in recent years. It might be in part because I kept addressing people that way, and they got used to it...
