I have always done my first oil change at about 500 miles. Knowing Ford doesn't use anything special from the factory for oil, there is no concern changing it early. When you change it is purely something of personal preference.

I'm confident that if you were to compare engine life for a vehicle where the owner did the first oil change at 500 miles vs one that was changed whatever the factory recommended mileage is. That you will not find any significant differences in overall engine life or number of engine related issues. Tons of money is spent by Ford in evaluation and testing to determine safe change intervals. And by safe, I mean one's that reduce THEIR warranty risks.

No matter what you do, you'll be just fine.
