iPhone 15 Pro, Apple Watch Series 9, and AirPods Pro 3 GPS and heart rate accuracy for workouts

I have the iPhone 15 pro, the Apple Watch series 9, and the new AirPods Pro 3. I am told that workouts will take the more accurate heart rate (AirPods or wrist), but it does not take the more accurate GPS of the watch and phone. I always run with my phone, why can’t Apple do the same thing with GPS as it does the heart rate. I have to use phone plus AirPods only for more accurate heart rate and gps data? (And throw away my watch?) also I want the cadence and other watch data to be included. Shouldn’t Apple (since it is being advertised as working perfectly together) have all options work together. This would make it the best possible workout setup on the market, instead now it looks like a scam where I bought all of these new things but I need the Apple Watch Ultra (spend an extra 300) to get the proper GPS on the workout. What a messy set up!
