It's probably good to start with XYZ, but we have much better colorspaces now that do a better job at correlating with our vision.

Mainly CIE 1976 L',u',v' and even more recently ICtCp from Dolby research.

I don't think starting with XYZ and color matching functions is a good idea. LMS and cone response functions are a more fundamental and intuitive description of human color response, so if you're going to bother with XYZ at all, you should arrive there from first principles, via LMS.
