Are stream ciphers no longer considered by NIST?
I don't know, but block-cipher based modes of operation have seen a lot more scrutiny.  AES in CTR mode has been vetted much more thoroughly than any of those stream ciphers you mention.  Moreover, those stream ciphers do not offer compelling benefits over AES-CTR mode.  Therefore, it seems to me it would be entirely reasonable to focus on block-cipher based modes of operation.
