You could place your machines as part of the wall and have the wires one deeper as well. But yeah, CF on cables(which hasn't always played nice) or Immibis Microblocks(which has always played nice in my tests with damn near everything I could throw at it).
Plus, CF looks kind of ugly. And unless your base is made of it, it really stands out.*
*Depending on what you build your house with, it can kind of blend in, but still, use Immibis Microblocks, you can have your wires hidden in your walls and still have a nice looking house no matter what your house is built out of.
