It seems to me that a woman’s ultimate accomplishment/purpose is the same as a man’s ultimate accomplishment/purpose. The nature of that ultimate accomplishment/purpose is a machlokes between (and I am sure there are other shittos out there) the Ramchal (to come close and derive pleasure from Hashem) and Rav Shamshon Raphael Hirsch (to aid the Klal). The difference between the men and women, in general, is in the path to that accomplishment. However that is only in general terms describing the bulk of kahal, not an individual prescription.
Back in the days of yore when there were neveim one could go to the navi to find out one’s path to the ultimate accomplishment, but nowadays, because of our many sins, we do not have neveim and therefore it is much more difficult to find one’s path.
