The Desktop SDK Team has just posted a very helpful new community sample which demonstrates how to work with the ArcGIS Pro Cartographic Information Model (CIM). The new sample is located here in the Map Authoring section of the Community Samples. It presents some nice examples on how you can work with renderers in Pro.
Also, in order to use the sample, you'll need to download the latest version of the community samples dataset which is located here.
