I would say that this is a personal preference type of thing. Since
the CG is a military organization, only the top brass gets to have a
preference, and everybody gets to be trained to do it that way.

I prefer north up because when you turn the boat, the chart plotter
doesn't change around. But you need a really good "boat" symbol drawn
on the screen that shows the heading very clearly.

Either way can be "intuitive" if it matches how you think it should
work.

1) You want to watch a boat symbol Use North up
wander around the electronic chart.

2) You want to look at the world like Use Heading up
you have x-ray vision.

Training and practice is the way to make either way work for you. Also
teach each person how to check the mode and change to their
preference.
