This is going to be an easy question, but when adding host networking, 2 of the 3 choices are:

Physical Network Adapter
Virtual Machine Port Group for a Standard Switch

What is the effective difference between these two settings? The wizard screens look exactly the same and ask the same questions.

Yes, I get that, but If I want to create a new vSwitch and tie a physical adapter to it, it appears that I can accomplish the same end result by using either of those choices. Just trying to understand.
think of the standard switch, what we often refer to as a vSwitch.

This is the same as a physical switch in the physical world, a switch with many ports (24/48) that you can attach computers to - this is the Virtual Machine Portgroup.

virtual computers can share and communicate with each other across this switch, BUT if the virtual servers need to send data elsewhere in the network outside of the physical server, this vSwitch needs to be uplinked to a physical network interface in the host server.

does that make it clearer ?

A virtual machines network interface MUST be connected to a virtual machine portgroup (which is labelled), which is connected to a vSwitch, and the vSwitch must be connected to a physical network interface in the host server.

You cannot (well you can!) connect a virtual machine directly to a network interface on the host....

You want all your virtual machines to share a switch, which is connected.
