With Shimano or SP, you've got to either twist the cable ends for the light and charger together, then fit the plug block to the twisted ends. When you remove the charger, you open up the connector and untwist the wires. Doing this repeatedly will damage the end of the wire, and eventually you'll run out of cable to trim back.
Alternatively, you can fit a DIY connector somewhere along the light cable run. This would be a potential source of connection problems from water or whatever if not done well.
The SON lights are available with coaxial plugs on the end rather than spade connectors, for use with the new coaxial connectors.

There's a link to the drawings below each column, in which you can see the 50 mm flange spacing
The 1.5W hubs are really only intended for utility lighting. You shouldn't expect to be able to charge anything usefully, and I doubt you would get the full 80 lux from a Cyo either.
