"Cycling as a female Vs male also has its benefits, for example a lower average weight = easier on the inclines. "
Well no.

The average 18-29 yo woman was 65kg
And the average man was 80kg.
18.5kg of lower body muscle in the men.
12.5kg in the women.
Bike weighs 9kg, say, no difference between men and women there.
Male: 80kg + 9kg = 89kg. 89kg up a say 5% hill is 9.8067 sin arctan 5% 89 = 43.6N
Female 65kg + 9kg = 74kg. 9.8067 sin arctan 5% 74 = 36.2N
Divide by muscle mass:
43.6N / 18.5 = 2.36 m/s^2 male
36.2N / 12.5 = 2.89 m/s^2 female
So it's about 23% harder for a woman.
By age 40, both sexes have typically put on 10kg without gaining muscle mass. This is then 2.64 m/s2 male versus 3.31 m/s2 female.
So a fat middle-aged bloke (BMI 29) can still climb hills easier than a young woman of healthy weight (BMI 24).
He'd have to be in the obese range (BMI 34.8), and bordering on extremely obese (BMI 35+) for him to be doing as much work as a woman of healthy BMI (BMI 24).
