Regular WAV at ~CD rate is limited to about 5 hours because the length

I'm a little surprised sox doesn't do that by default.

I wasn't aware that WAVEFORMATEXTENSIBLE covered file sizes - the spec seems to be mostly about "higher resolution" sample formats. what did i miss?

more portable solutions, i think, include using w64 format or even CAF, which are both defined with (unsigned) 64 bit file size limits.
