There is no magic, I agree. But you do see useful characteristics become widespread. Roots are helpful for plants, and motility is helpful for animals. So these are common, though not universal. There are plants without roots, and there are sessile animals, because there are so many environmental niches you wouldn't expect anything to be entirely universal.
As for "objectively beneficial", this is an oxymoron.

You see useful characteristics become widespread if mutations actually develop for them early in the evolutionary process of life on earth. Intelligence is widespread, for example. It's also highly complex. We still don't know exactly which genes human intelligence is dependent on. Probably because intelligence is a wide umbrella term for a variety of functions that work together but are not necessarily tied to each other genetically.
