Moving passages into some sort of string container or else needing some
sort of specific quotation style in order to preserve literal content
seems like a frequent problem.

How about defining some prefix to be used right before C-w or C-y and
related commands that will then strip/interpret the respective suspected
quote sequences going into the kill buffer, and add them when going out?

It would likely need some well-defined mode-specific hooks providing the
string-packing and unpacking, defaulting to something working reasonably
sanely with the union of C and Elisp strings but hopefully taken up by
most mode providers eventually.

Having a standardized mode-specific view into stringizing and
unstringifying passages (prefix arg for specifying the particular quote
style defaulting to " (2) in most modes?  Something like an input method
selector for that?) might be useful for other generic functionality and
keybindings.  But at the very least a standard for "-quoted strings
seems like a good idea.
