Disconnect the connectors first.

In case it isn't clear, the part on the left attaches to the hub and stays on it when the wheel is removed. The plug part needs soldering to the cable from the light or device and it isn't apparently the easiest job - I got someone who does it for a living to do mine.
I have hubs from SON, Shimano and SP-V, I can't feel any difference in function between them.

Why would you need to disconnect the dynamo from the cable at the hub (other than for a puncture)? Are you intending to have cables permanently mounted on the bikes in question? That would not make sense to me, because it would result in the loose connector(s) needing to be secured out of the way of the rotating hub/spokes. Similarly the connector at the other end for the E-Werk would be loose/dangling and vulnerable to damage.
If you are fitting the dynamo wheel to a bike only when needed, moving it from one bike to another when needed, and it is only used to charge an E-Werk, then leave the cable attached to the dynamo. When you fit the wheel to a bike, just coil the cable around the fork leg three or four times (maybe securing it with electrical tape or a cable tie) and run it to your handlebar bag which will presumably hold the E-Werk.
For such use I would prefer the standard crimped spade connectors to any of the other options, including the plastic Shimano connector block. The overwhelming majority of people with Son hubs use the standard connectors, and disconnecting and re-connecting for a puncture is not particularly difficult.

If you do - and there's arguments for and against - I'd just leave it on the bike all the time. It's a common idea to only fit a dynamo wheel when required, it's also common for people to change the plan and not actually do so (I did myself). First the drag (As you'll have discovered with the Shimano) isn't as much as some would have thought, then the reliability is such that I got at least 50,000 miles before needing a service (SON Klassic), lastly it's just a faff. On my bikes disconnecting spade connectors would be less effort than removing wiring I've taken the trouble to do neatly.
I use my dynamos primarily for lights, though I have a charger it's just used as a back up. If I was using a wheel just for my touring (Probably no more than 3,000 miles a year) I'd happily use any of them.
