Here's some further thoughts on the Wago connectors. First of all, I did not realize they also have a "lever nut" type that appears to make it easy to remove the wires (just pull up the lever?). Never saw that version. I just went to Home Depot and purchased the ones that you just push the wire into. Once that is done, can't remove it, so must cut the wires. And yes, this does not apply to tapping into an existing wire. That's where I like the Posi-taps over the suitcase connectors. They are more expensive though.
Hope this helps.
