(note that I used some other standard opening for white that I commonly use and they're all 3-4 openings)
After this opening, white usually approaches at a,b,c,d or e with a being the most common.
Understanding (not knowing, there's a big difference) all the 3-4 approach joseki would put me at a significant advantage against my opponent because I can choose a joseki to play which will give me a result that's AT LEAST equal if not better for me. And if my opponent makes a mistake, it only makes us go into the game with a significant advantage for me.
And since I already have a reasonably okay understanding of attack and defense, I should be able to get a pretty good lead mid game, or at least not fall too far behind.
Does that make sense?
For the context of full-board fuseki, you might find it equally if not more useful to get a pro game database (GoGoD is very good, but there are free ones out there as well), install Kombilo, and search for the position there.
In fact, you can even hack eidogo to do a full board search, by clicking-and-dragging a region that touches two of the corners and almost touches the other two, as seen in this screenshot.

, then B also has (c).
a or b either leave
stone might be fun for black. Alternatively, black can make a base on the right with the
stone.
