For that I have an ever growing collection of USB-C adapters. A to C, C to A, C to Micro, C to Mini, C to B, all kinds of angles, etc. All the adapters take less space than one extra cable and I was able to get rid of all non-C cables.

I am down to just a couple of devices that don't have USB-C and it's wonderful. I also modded some devices with USB-C charging ports using USB-C PD trigger boards so I won't need barrel plugs as much anymore.
