Current Rohloff are less noisy on their 7 lowest gear than older ones. I have two bikes with a Rohloff, he first one of 2021 even if it now has a lot of km remain noisier than the second one of mid 2016.

The break-in time of current Rohloff is also much shorter that it was with the first models.

If somebody will build the wheel for you, it is strongly advised to add the flange support rings
