What's the name for installing a roll pin in the direction of a
shaft,
sort of like how a square key sits? That might be the lazy next
option.

Dutchman or Scotch key.

Good luck drilling straight along the seam between different
materials.

Around here a Dutchman is an inlaid patch, most often a repair to a
defect in a wooden piece. I know the device under discussion as a
Dutch pin.

The problem drilling the joint between different materials can be
minimized by starting the hole with an end mill as close as possible
to the desired size, then enlarging, if necessary, with a drill. Still
can be pucker-inducing.

My preference is for a tapped hole and set screw instead of a pin.
Easier to disassemble, less fussy than fitting a pin, and also retains
the mounted component in the axial direction.
