I would never use a non-synthetic oil for break in unless the engine manufacturing processes required it. An example would be the older M models. Mineral oil was used for break-in there because of the cylinder wall finish. The whole BMW 1200 mile break in period recommendation, which is still driving some owners to change perfectly good oil in, was based on that premise. Current manufacturing techniques have no requirement for mineral oil for break in. Your engine is already being broken in on a full synthetic, as it should be.
Use the best oil you can, and at the moment, that is a full synthetic. See ard's recommendation. Look for the API symbol, and if it is a diesel, the LL-04 designation. Don't use LL-04 if it isn't a diesel. Since you are in the warranty period, it is advisable to only use an oil that is specified by BMW, no reason to create drama with them if you ever do have an engine problem (not that oil is likely to cause one, but why create issues?).
No requirement to change motor oil viscosity during the year in the NE. You can get a multi-grade that will cover all of your ambient temperature conditions.
If there is any miscellaneous crap in the filter after BMW cleans out the engine after assembly, then it isn't like you need to change the oil to take it out. It is supposed to be in the filter, that is what the filter does. If you want to, just change the filter. If you want to change the oil, fine, no problem, but it would be for the pleasure of doing it, not for any benefit to the engine.
