I wasn't taught how to throw a ball as a kid, but as an adult I worked in the U.S. for three years and my son went to Little League. I learnt by watching him learn. Now we're back in the UK and he's an adult, we still play catch in the field behind our house in the summer.
You left out a critical cause of throwing like a girl: the elbow carrying angle. In males, it is between 5 and 15 degrees while in females it is usually more than 15 degrees. This difference is present as early as age 5 https://pubmed.ncbi.nlm.nih.gov/24899327/
Another difference is implicit in your summary but deserves to be pointed out: beginning in early adolescence, females have smaller shoulder girdles and less powerful muscles, meaning that with the same-sized projectile, girls and women will naturally gravitate towards a “push” mechanism because the weight is more likely to exceed their strength limit.

Some of it is that women's arms hang at a different angle than men's' arms.
