Yours is a common question, but many practical shooters would reject the premise. There doesn't need to be a choice of accuracy or speed, and as people develop their skill, both improve. Often people start with a tendency to focus on accuracy or speed, and can be categorized as either a turtle or a hoser. Turtles take as long as needed to ensure accuracy. Hosers like pulling the trigger more than hitting the target, and faster is better. There is some argument about who is easier to train up to be a skilled practical shooter. Is it easer to make a turtle go faster or make a hoser slow down?
I think it is possible to train both accuracy and speed, and it is very inefficient to focus on one or the other. Once you can aim the gun and hit the A zone at 7 yds, you're ready for the next steps. What are those steps? 1) Find a good instructor. As the Mandalorian says, "This is the way."
There are also some good books. My current favorite is Breakthrough Marksmanship: The Tools of Practical Shooting by Ben Stoeger
