No, even for emacs-lisp code blocks I use C-c ' to edit the code in
emacs-lisp mode.  I do have "[" and "]" globally bound to
`insert-parenthesis' and `move-past-close-and-reindent' respectively,
but that's probably a little too radical for most users.

I only enable paredit minor-mode in lispy modes.

Not quite,

Paredit has a number of nice features aside from sexp movement,
including /electric/ insertion of both open and close parenthesis,
brackets and quotation's which greatly increase the speed with which one
can write lisp code -- all the while ensuring that the code in the
buffer is /valid/ in terms of balanced parenthesis.
