It depends a lot on the school the girls go to (or went to) and the home environment. Also, once one gets used to reading english, yiddish becomes more cumbersome to read EVEN IF YIDDISH IS HER FIRST LANGUAGE. Besides weeklies such as das yiddishe licht, oneg shabbos etc. there are monthly yiddish periodicals such as maalos and I think der blick. I’m not sure about der shtern because there was a whole ruckus that it’s just history and politics with no Jewish values. And nothing compares to the quality of say mishpacha, but they are all more tzniusdik and the hashkafa is definitely anti-israel.
I believe most men prefer yiddish, although there are always exceptions, especially if it’s “in house”.
