I noticed that in the list of unlocked Storylets that always appear below the Opportunity Deck, some are yellow and some are plain white (or cream, I suppose.)
What is the difference between the yellow ones and the plain ones? Should I focus my attention on one or the other?

TL:DR Yellow (or Gold) Storylets are part of a larger story arc, so it might be more interesting to pursue them, if you can. If not, try some plain white (or cream) cards to build up your Qualities and Traits.
As far as I can tell, there are four different types of Storylets, each with their own colour (note that I present some out-of-context examples, which might be considered slightly spoilery):
Side Note: Some white Storylets act somewhat like gold Storylets, in that they are only playable once and progress along a larger story. A way to distinguish them from normal white Storylets is that these type of Storylets seem to require a very specific quality, and when completed they will advance that quality.
Here is an example of the Storylet I'm trying to describe:
