(Attempting to recover) perfectionist checking in here.
I've found most of the discussions regarding the "best" application of a given cast-on in...BOOKS. Not online. My first suggestion is to visit your local library and simply make yourself comfortable with some reference books in the 746 section (includes knitting, crochet, and other needle arts). Look at the "cast-on" section and see what's recommended.
Second, if your local library doesn't have a good selection, ASK the librarian how to borrow books from neighboring libraries. ASK her/him the best way to find, via the (probably online) card catalogue, good knitting reference books. Then proceed as with Step One.
