RE "....Cutting and laying out wires are some of the most tedious and frustrating process....." I would be investigating to use wire wrap. I built some circuits using wire wrap, back in late 70s ,early 80s. I designed and built a circuit on a wire wrap prototype board to put a 68008 DIL chip on the Apple II bus. I'm not sure of the cost of wire wrap parts now - may be quite expensive , the special wire wrap sockets etc .....
