I did mine at 3k, seemed like a good medium between being unnecessary and a little early.
That's usually approximately what I do.
2000-3000 miles on the FF, then use whatever oil I'm going to use.
More important than changing the FF at some arbitrary mileage, IMHO, is to pay proper attention to engine break-in in order to reduce the likelihood of the engine using oil over its lifetime.
I do that by gradually increasing the RPM, not being afraid to touch redline, as long as the engine has been properly warmed. As I put more and more miles on it, I spend more time in the upper ranges of the tach.
The worst thing you can do is baby a new engine. That doesn't mean to abuse it, but some quick trips to redline, even with torque potential.
Another thing that is very important for piston ring seating is engine braking. That is, do it a lot. Your engine needs that vacuum to help seat the rings.
Also, you need to vary speed, gear, and RPM a lot. Don't get on the interstate in your new car and drone for 500 miles at the same speed in cruise control. Take backroads, again, varying speed, gear, and RPM.
Using these principles, along with frequent oil/filter changes with good synthetic oils, I've broken in 3 new vehicles and a few new motorcycles (2004 Honda Accord K24 5-spd, 2007 Tacoma V6, 2016 WRX 6-spd, 2004 Honda 919, 2005 Yamaha R1, 2007 Yamaha R1), none of which had any oil usage problems.
