Check out Karabiner Elements (https://pqrs.org/osx/karabiner/).

You can create a rule to change caps lock to control if pressed with other keys, else escape if pressed alone.

I have no affiliation with it, just ran into this issue myself and it solved it for me.

That kind of highlights an issue for me though. If Apple were really on the ball with macOS they would have a better remap utility built in.

Instead we have Karabiner Elements which has been of mixed stability in my experience.

Many times I've had it completely disable the internal keyboard on my late 2013 MBP to the point where I have to plug in a USB keyboard to recover or if on the road do a force power reset.
