Consider use of ‘dietary needs’ in following sentence: “I share some of my food with my dog, though in limited quantities since his dietary needs are different.”; while domestic dogs do have different dietary needs than humans in the strict sense, the intent is to convey a softer meaning, as there is overlap hence being okay to eat some of the same (atleast in in the dog-to-human direction —and chosen wisely indeed healthier albe more premium and pricey than gourmet dogfood, whereas less purposeful selections of human food not as much).
Something connoting a sense of an "optimality requirement" as contrasted with the default of a more severe "must-do requirement" implying dire consequence for failing to adhere or the other direction a desire-sans-need "want" would be ideal.
Whereas the default noun "needs" can be thought of as "need-to-haves", the meaning I'm after is approximately "ought-to-haves" (although I'm open to a verb or [re-]phrasal expressions fitting the meaning as well, preferably succinct) while still suggesting some nontrivial degree of necessitation.
