1) Efficiency vs Unpredictability

Why is unpredictability a good thing? Is this something where you're playing a game with another agent and you don't want him to predict what you'll do?

2) Speed vs Accuracy

I don't think those are opposite. They'll occur in tradeoffs, but only in the sense that any two things will. There's also speed vs cost, or speed vs documentation, etc.

5) Surely Some vs Maybe More

I believe this is normally stated as "Risk vs Reward".

Yes, exactly. Kind of narrow, but I just find it really cool. And, lots of things decision makers have to do can be formulated as games with other agents.

I don't think those are opposite. They'll occur in tradeoffs, but only in the sense that any two things will. There's also speed vs cost, or speed vs documentation, etc.

I agree that they might not be "intrinsic", but if they're very commonly inversely correlated in situations we care about (which I think they are), then considering it as a trade-off can still be useful. See here for more.

"Risk vs Reward"

Thanks. I'll make this explicit next time. I like to have an upside connoted by both words of the trade-offs, which is why I didn't like risk vs reward.

Come to think of it, "Risk vs Reward" is oddly-worded. It's both vs neither. If you had to choose between the two, you'd pick reward every time.

That's because there ain't no such thing :-) there is no "vs" there.

People usually talk about risk/reward ratios. The trade-off is between a larger reward with more uncertainty and a lower reward with less uncertainty. Your preferences in this trade-off are often described as risk aversion.
