What is the point to such a question? It doesn't matter what you are shooting the physics are all the same regardless whether you are shooting macro in a studio or birds in a forest. 99% to photography is preparation. The types of photography you listed ultimately depend on it for success.
Once Ricoh/Pentax finally moves to UHS-II in a KPII all the things people think are wrong with the KP disappear sans for the grip. The biggest obstacle using the K-1 is the camera is so slow to function entirely due to the UHS-I bus. I am always waiting on the storage bus to finish whether I have taken one image or half a dozen. There is no buffer problem. The sensor isn't to slow. The UHS-I storage bus is so inadequate the K-1 is always slow to respond from waking up the camera to single drive mode shot to shot. This isn't my experience this is what everyone is experiencing that is using a K-1 or KP.
Here is an example when shooting in Pixel Shift Mode it takes the camera around 5 seconds to recover. The actual Pixel Shift Capture and process is pretty instantaneous shooting at speeds faster than a second. What is taking 5 seconds is writing the 150mb file from the buffer through the slow UHS-I bus. Once Ricoh/Pentax moves to UHS-II it will only take one second for the camera to recover.
There is a lot more to UHS-II besides the needed bandwidth that greatly improves response time namely the second set of pins that allow bi-directional communication with the SD card. This will all transform handheld Pixel Shift. And everything else the perceived slow autofocus or perceived need for a larger buffer. Improved battery life. The GRIII is an example of why UHS-II is needed in that regard.
