Sounds like you're choosing the "cream of the crop".

From what others wrote, I like "select", "cherry-picking", and "blessed". I don't like "filter", "screen", or "cull", because they imply getting rid of (bad) stuff; you probably want to concentrate on the good stuff.

What qualities are you wanting to measure when determining what's important? I'd brainstorm in that direction, if that's something that can be determined ahead of time.

If you're doing something like an aggregator that puts the good stuff at the top, then "cream of the crop" would be good as I said, or make something up like "cream of the top". Or something about slicing off the top. Or other things that might have good/better stuff at the top: ice cream cones, cupcakes, shakes, lots of garnished food.
