I am attaching the Gerber print pattern for review ... I think it looks OK, but this is my first attempt. The holes for the "Power Input" seem larger than expected, but the part is a standard from the "Core" library ... I think from Sparkfun. Don't think it will present a problem.
Even the "holes" from inserted parts are properly indicated.
I did correct the wiring for the Vin and Vcc connections, and am including the Fritzing files as well. Thanks for helping me understand that a bit more clearly. Some of the components will still get 5Vdc ... specifically the LCD, but that is within specs.
