I was taught, and always use north up. All of my peers also use north

Are you talking about radar or charting ?

Both.

The vast majority of small boat radars display only in "heading up"
mode.
I don't know about the "vast majority" but my entry level Raymarine
SL70 installed in 1999 has North-Up, so I assume all Ray's sold in
this century have it.
