Electrical Code for wiring multiple outlets
The Code requires that continuity of the ground wire (equipment ground) cannot depend on a device.

The Code also requires that the continuity of the neutral (grounded conductor) cannot depend on a device if you are using a multi-wire branch circuit (Two hot legs, a neutral, and ground).

The Code never requires the continuity of the hot leg to be continuous.

So, that means if you are not using a multiwire branch circuit then you can use the clamps on the devices for the hot and neutral. The ground would need to be pigtailed on every device but the end of the line. If using a MWBC then you would also have it pigtail the neutral on all devices but the end of the line.

Wago, Ideal, and other push-in connectors are UL listed for use and can be used for joints in an electrical installations. Or you can use wire nuts. The choice is yours.

Good luck and stay safe!
