Not only that, he is called the mightiest of all the Children of Ilúvatar [Sil. ch. 11, p. 112].

Sure there is. It is said that "she was the mightiest and fairest of all the Elves that remained in Middle-earth" [Sil., p 370] for instance.

Then Elros is not a Man if this is your logic. Elrond is an Elf, he chose to be so, as is said in Appendix A;

"At the end of the First Age the Valar gave to the Half-elven an irrevocable choice to which KINDRED they would BELONG. Elrond CHOSE to BE of Elven-kind"

Elrond is called the Half-elven because of his descent, but he IS an Elf, and chose to be so. Just has Elros is also called Half-elven, "Elros and Elrond, the Peredhil or Half-elven." [RotK, App. A] but he IS a Man because he chose to be so.

From the Silmarillion, "In Middle-earth dwelt also Gil-galad the High King, and with him was Elrond Half-elven, who chose, as was granted to him, to be numbered among the Eldar" [ch. 24, p. 315]

I would think because a group of the Númenóreans were Half-elven as well, though as we know they were in any case Men, in this case, High Men or Kings of Men, Dúnedain. Take for instance Erendis, a Númenórean, who says of the Men of Númenor, "Men in Númenor are half-Elves (said Erendis), especially the high men; they are neither the one nor the other." [Aldarion and Erendis, p. 216]
