CGJ would be better used to prevent canonical compositions but it won't

In the question, visual difference was desired. The Unicode FAQ says:
“The semantics of CGJ are such that it should impact only searching and
sorting, for systems which have been tailored to distinguish it, while
being otherwise ignored in interpretation. The CGJ character was encoded
with this purpose in mind.”

So CGJ is to be used when you specifically want the same rendering but
wish to make a distinction in processing.
