newfs actually doesn't reformat; it just rebuilds the filesystem. I don't
think ccd supports formatting, though in theory it could pass such
commands down to its member drives. You are unlikely to need to format
anyway, especially with disks recent enough to be terabyte-sized.

This is a limitation in the partition table; it has a 32-bit limit that
means it cannot represent a partition over 2TB. (The limit may actually
be one sector less than 2TB; I haven't bothered looking in enough detail

The most expeditious thing is to use the raw partition. Since you wrote
to port-amd64, I assume you're using amd64, in which case this will be d,
so you'd use ccd0d (or ccd1d or whatever). Of course, this works only if
you don't mind making the whole ccd a single filesystem.
Another alternative may be available, depending on what NetBSD version
you're using. I've seen GPT support described as, among other things,
raising this limit; if your NetBSD includes GPT support, that may work.
(I don't know how you'd go about using it; I've never played with it.)
