Amazing to me that this 2014 video is still relevant and useful in 2020!

People look at the superior position of a Ridge Board and assume it's structural, it's not. It's simply a place to put the marks, to locate the rafters. A ridge board could be made of cardboard, except that it would be hard to manage on site, so typically, (we used) a 1x6 or 1x8 by the longest lengths available. A 4" x 6" timber would be wrestling a lot of mass for nothing, from a ladder. That's the only criticism I can see here, this is good stuff.
