Yeah, a hermie plant will make feminized seeds. But, they will have a tendency to stress easier and go hermie themselves. I wouldn't bother growing out/making seeds from a hermie, we put too much time and energy into growing to have it ruined by shaky genetics.
I just completed a harvest and newbie breeding project. Did about 30 crosses or so (went a little overboard).
Here are my 2 favorite looking seeds.
This is Purple Diesel X (Jack the Ripper x Purple Urkle) Almost completely black
This is (Jack the Ripper x Purple Urkle) X (Plushberry x Headband) I like the thick defined tiger stripes on them
