I'm pretty sure you could set up Windows to do that in a few minutes.
Not that I am aware of ... but I do know Powertoys will let you enable Xmouse.
For those unfamiliar, Xmouse focuses a window if the pointer hovers above it for some timeout (e.g. 250ms).
In any case, that wasn't the point. The point is, Cntrl+C/Cntrl+V is not terrible...and I wouldn't suspect "Cntrl+Click" is bad either.
