I would use the factory oil until at least the recommended first change interval because it's usually not full synthetic cause in past you don't want to break in a new engine with full synthetic. But if they regularly use a blend then I definitely won't be taking in my car for oil changes. Over 30 years of using Mobil1 and my current daily with over 320k in 11 years.
When I was into bikes, they would say drain and change at 500 and/or 1k because that's when you have the most metal in the oil because parts are mating. Maybe overkill but I love working under the hood anyways and 5 qt jugs of Walmart and filter is cheap insurance.
Do manufacturers even use "break-in oil" in their engine oil?

You can go to different oil websites and see the brands of cars that use their oil for the factory fill. I also think the days of "break-in" oil are behind us.
Mobil 1 treated me great in the SS 1LE. Shell Rotella was great in the STi. And now I use Castrol Edge 5w30 Euro Formula for the 240. I'm a firm believer you can use the cheapest no-name brand oil in any modern car and as long as you change your oil every 5-8k miles (synthetic) you'll be fine - I just don't want to do it. LOL
