But Mac OS (Xerox PARC) invented cut/copy/paste/undo, and defined the keys to be Cmd-X/C/V/Z. Instead of trodding upon well-established conventions (including those in use in the Apple II-][-// world), they made their own new ones. Microsoft didn't make their own keyboards (at the time), so was at a bit of a disadvantage when they copied the functionality from Apple. They didn't have to choose Ctrl, but they apparently decided that multitasking and job control were the domain of non-personal computers and not their problem.
