Sentience, intelligence, and language are not all directly related, and their intersections are largely the realm of philosophers, cognitive scientists, and sci-fi enthusiasts. Singer denies that sentience is relevant in moral philosophy, and sentience itself can be variously defined: there is a Buddhist concept, which differs from the Catholic concept, which differs from Freitas' concept, which differs from Roddenberry's. I would also dispute that dietary taboos are based on the intelligence of the meat. The domestic pig is "smarter" than the domestic dog, but found in many more cultures' cuisines. And there's more I would object to, but that's all beyond the scope of this site. Let us say you mean human or human-like, comprising whatever qualities your preferred philosophical and moral system may identify as making a Wookiee, a goldfish, or SkyNet "human enough," be it responsive interaction, moral agency, bipedalism, or an appreciation for green Orion women.
Humanoid is a morphological term, and sentient, conscious, cognizant, or sapient are all philosophically vague. In English, those entities who possess "human-ness" are broadly beings (e.g. human beings, but also angels, mermaids, Mrs. Whatsit, or laboratory rabbits to various subsets of the population). That would be a tricky root to use, however. Para-anthropic might be better, or we could borrow a term from a specific tradition or discipline, like sem chen or sattva.
English words for describing an organism based on its dietary consumption fall mostly into three camps:
- the -vore, from the Latin vorare, "to devour": insectivore, saprovore, omnivore
- the -phage, via Latin from ancient Greek φαγεῖν, "to eat": myrmecophage, saprophage, autocoprophage
- the -eater, the agent noun of to eat: anteater, lotus eater, man-eater.
(Cannibal is an anglicisation of a hispanicization of a tainoization of Carib, rather than a term inherited or constructed from roots).
And that should give you room to coin a term to your liking: sentientivore, paraanthropophage, sattva-eater, and so on.
