The fillet tool in Fusion allows you to do G1 and G2 but does not provide any scale ability to massage the curvature comb.

G2 is more or less not as useful when I cannot sculpt the flow, and the default result in Fusion is not ideal.
Below is an Alias screenshot with the default blend curve with a nice and smooth flow.
I also activated the G1 G2 handles so I can change the shape if desired like in the right image!
