The only proofs of the C-M thm I know of are the original paper,
and the one in Weinberg Vol-III. Both essentially come under the
scope of (orthodox) axiomatic QFT.

I've heard vaguely that C-M thm (or something like it) also applies
within other formulations of QFT. If that's right, can anyone here
suggest references?

TIA,

Here's another proof on arXiv, probably similar to the others:

Various formulations of QFT are supposed to be equivalent. Some are easier to use for some problems than others, but they are supposed to be equivalent.
