Well apple as it turns out doesn’t really need additional nutrient, it’s very nutrient rich already. Same with cherries.
However it won’t hurt anything but it’sit’ll make your apple ferment a little more vigorously.
I am a fan of using "just enough" nutrient. Anything that isn't consumed by the yeast is going to be left in the end product.
DAP is argued to be carcinogenic. I don't know if that is true or not, but I don't necessarily want any more than necessary floating around in my drink.
I am a fan of using bee pollen as a nutrient. It provides all the necessary nitrogen and micro-nutrients that a ferment needs. Additionally, for mead's it is more of a purist's nutrient for traditional meads that are nutrient deficient without the addition of nutrients.
