Answer 1

Nested IFERROR functions can handle the variety of number ordinals.

=--SUBSTITUTE(REPLACE(A2, IFERROR(FIND("st ", A2),IFERROR(FIND("nd ", A2),IFERROR(FIND("rd ", A2), IFERROR(FIND("th ", A2), LEN(A2))))), 3, ", "), ", ", " ",2)

I used a custom number format of [Color10]mmmm dd, yyyy hh:mm:ss.000;;;[Color3]@. Beyond the fact that the text is left-aligned and the true dates are right-aligned, this will put text-that-look-like-dates in a red font and true dates in a green font.
