I'm 6'2" and have 8+ inch wrists. Nobody reads me as male anymore. My cis wife is almost as big in the wrist department and 5'11". She also normally gets read as female.
I wouldn't worry about things you can't control. Focus on what you can do with what you have to work with, and the scales will tip into the "F" zone. Mannerisms, beard removal, voice, makeup, clothing and hair really do go a long way.
