It really helps prevent many mistakes if you have a scale drawing
instead of a picture in your head. ;~)

This. I always sketch out what I'm planning to do, with
dimensions, before I start. Pencil and paper, because
I'm old-school. And generally not a true scale drawing
(I could do that, I worked as a draftsman a long time
ago), since I find as long as I work out and record all
the dimensions, I don't need it to be scale.

I was never a draftsman but was headed in that direction when in school.
The trouble with paper and pencil is that the drawing, and especially if
not to scale, only gives you an ideal/concept. It does not necessarily
give correct dimensions. You can put dimensions on the drawing but if
not to scale you have no way to guarantee if the drawing is doable with
the dimensions you want.
With software you have the ability to have the program double check your
thoughts.

Yes, and you can even do the jointery in software so you get those
dimensions right, too. Doing everything is software first saves a lot
of trees.
Properly programmed, the software between your ears can do every bit
as accurate a job - and for the older ones of us it can even be done
more quickly.

For trivial projects, perhaps.
And exactly what did the craftsmen of yesteryear do, before computers
and CAD??? They did the calculations in their heads, and drew
"diagrams" showing how it was to go together. A lot looked like
leonardo Davinci's drawings 0 dimensioned but not accurately scaled.
