You will have best success if you limit the focus fields to those of the subject and limit the lens' focus range to the expected distance, tick the tracking to sensitive, tick switching of focus fields to rapidly, tick priority to shutter release instead of a balanced setting between shutter release and focus accuracy.
Approach the settings step by step. If you want to cover 50% of the image area anyway, it's probably enough to switch between the 5 zones North, East, South, West, Center. If not, limit yourself to 3 focus points per camera orientation and switch them to single-point or af-point expansion: You can store a focus field so that it is activated when you press a user-defined button. With the other field you can jump back and forth between a selected focus field and the center focus field. I don't quite understand, at a point where I'm wondering if your example isn't constructed, why you have great difficulty with f/16 and autofocus when the autofocus also focuses you approximately near the object.
After all, with the autofocus you could only follow the object if it is within the desired composition, i.e. at a distance where you keep your focus. This also prevents pumping, since you as the user limit the focus drive to a small range.
Aperture f/16 is an unnecessary handicap for the required shutter speeds for objects moving so fast!? You could try to prioritize a fast shutter speed with auto-iso and shoot in mode P, which optimizes for depth of field at the available light. If you feel up to it, shoot in manual and give the auto-iso enough room to choose.
Last but not least, google your specific purpose with your available gear. For example, you'll find tons of information for birds in flight.
