Eureka! Discovered, or realized, the connection I was looking for!
The Classes or Nodes may not have a built in method to reveal what properties they have available, however the properties are the class attributes directly.
By looking at the API Class documentation, or doing a python dir of the class in question, you can see the properties available. Yes it will list everything, but you can easily see which property name it is you desire to make use of.
Obvious reminder, Definitely use the
<asset>.set_editor_property("<property>")
methods to allow the editor to take care of extracurricular activities as needed.
Now off to figure out how to work with property connections!
