 comment Canonical Commutation Relations
Without wqve function, the setting is far too restricted. How do you compute the color of gold in the Wigner-Moyal setting, without having a wave function?

 comment Canonical Commutation Relations
The OP asked about CCR as part of a foundation for QM. You mentioned Wigner-Moyal. No matter what yuo meant by it, it either constructs a Hilbert space, then the CCR makes sense there but not as a postulate, or it doesn't, then it is a lousy foundation.

Wigner-Moyal still need to construct a Hilbert space to be a complete foundation, and then there are operators, and the CCR makes sense, though not as a postulate.
