Thanks. I had looked at that reference originally too but it does a lot of things unrelated to running Docker on WSL 2 and overcomplicates running Docker.

Realistically getting Docker to run on WSL 2 involves running a few standard install steps from Docker for installing Docker and Docker Compose v2 on Linux (such as Ubuntu, Debian or whatever distro you prefer) and then adding a 3 line shell script to your ~/.profile to ensure the init.d based Docker service starts when your WSL 2 process starts -- that's it.

I've been running this set up for months, it's super solid.
