Is there a right hand shortcut for copy/pasting on MacBook?

With so much focus on good accessibility on mac, it boggles me that there is no default shortcut for copy and paste for the right hand. On Windows Ctrl + Insert and Shift + Insert are copy and paste by default and Ctrl + Delete is cut. (Insert doesn't exist on mac keyboards so they would have to come up with a different alternative)

These shortcuts are crucial for people who use their left hand for mouse.

I was able to set up working shortcuts using Keyboard Maestro, but had a really difficult time coming to that conclusion. I even managed to set up a right hand undo (which Windows doesn't have afaik).

Does anyone know if there is a better way than to use this third party software?
