Number three not likely related to the grill block.

Unless of course an UG/SG has the ability to show fan on/off, then that would be the most useful

The LED fan light is a good idea as the UG does not directly show fan on/off. One thing I would recommend is that after the UG install is that you let the engine idle until the fans come on note the temp and also the temp at which they shut off. Also see if you can find the fan operating spec on line to verify what you observed. Some stock gauge only go outside of center if there is a significant temp increase and even though the fans are coming on may not rise above the center.
I live in South Florida, in the summer the cycling of fans at a stop light is normal on my car with the AC off, even without grill blocks. Several of my recent cars actually run warmer when the AC is off, this is cause by the continuous operation of the fan with the AC on. Even had one car the fans would run for a short period of time after the car was shut off.
All that to say in order for you to know what is outside of normal for your car you need to know what is normal.
