If you stand at the North pole and dig a 1 metre deep hole, moving you nearer to the spinning vortex of molten iron at the earth’s core that causes the earth’s magnetic field, have you travelled a metre North?

Depends on your choice of coordinates. In a polar NED coordinate scheme you have moved one meter down. In a cylindrical coordinate system you have moves one meter south.

If you held a compass vertically at around waist height as you stand in the hole, would the North end point at your feet?

No, but mainly because of physical limitations in the compass. They don’t work at all well above about 75 degrees. But if you were at the North magnetic pole and were to suspend iron filings in a heavy oil the filings would roughly align vertically, if there were no other strong magnetic sources nearby.
