If the screenshot shown is not from ArcGIS Pro, create a featurelayer that visually meets your requirements via the GUI, as described here.
Save it the layer to a .lyrx file, and view it with a text editor, examining the CIM classes therein.
Write code that instantiates the CIM renderer class, and set the properties to whatever appears in the lyrx file. Finally, use SetRenderer to assign the renderer to the featurelayer.
