Sequencer Curve Editor Resources

Hi, anybody know any resources that could help with creating dynamic, fluid animations inside Sequencer’s Curve Editor. This is for Product Animation like this example in Blender - https://www.youtube.com/watch?v=Vzyr6gtJcCc&t=15s , so camera swoops around product, fast spins with slow CU etc. Im struggling with keyframes and creating smooth animations. To replicate this Blender video I could possibly use a Rig Rail In Unreal?
What Im looking for is tutorials or resources that deep dive into Curve Editor for sequencer, how to use keyframes and curves properly, doesnt really need to be tutorials on UE specifically, but in general showing how to use Curves and Keyframes in a dynamic way for product animation. Any help would be very much appreciated, thanks.
