How should choose the suitable phy layer for bluetooth?

I am going to propose some solutions related to the IP for Bluetooth. I am proposing my solutions in layers of Host.

1. My problem is that how can i select the best phy for my solution? in my approach, I need to have long rage, low power and big packet transmission.

2. What are the main features offered with phy? what I know is that phy can impact on range, throughput, power. Is it all or is there anything else that I didn't recognize?

3. My devices are small and working with coin batteries. I do not have audio transmission. should I go with EDR PHY, BR PHY, LE 2M PHY, LE 1M PHY or LE Coded PHY?

4. Is it possible to use different PHY based on BL link quality to achieve specific application requirements? there is a paper entitled " Performance and Trade-offs of the new PHY Modes of BLE 5" showing that how to select the best phy based on the BL link quality.
