Lets start with the proper terminology. When designing in 3D you start with making a model, not a drawing 😉
For me personally the initial orientation of a component does not matter so much. Looking at the view cube, I usually orient it in a way so that what I consider to be the front lines up with how it is labeled in the view cube in the upper right corner of Fusion 360. In a 3D environment where objects can have any orientation it's not really so important.
If you do CAM work, make sure your coordinate system is set to Z-up. And maybe you want to orient your components so that they are oriented how they are in your main CAM setup where you do most of the machining work.
As to where do I start with a sketch, for me the main guideline is whether there are any symmetries. So all of the components in this assembly are symmetric about one plane so I'd make sure that sketches are centered, unless of course I am only making half a sketch and then mirror the geometry.
