Its probably the flow check
Re: Ghost or Gravity feed - not fixed with replacement TACO FLOCHEK
are the return lines above the circulators hot? You could be getting some ghost flow up the return.
If you have isolation valves at the pump turn them off if the returns are hot and see if they cool off?

Re: System 2000 oil boiler cycling on/off, what is normal?
Overcomplication. The dip switches on the bottom of the manager can be set to increase return temp. shutdown, approx. 155 to 170. Set high limit back to 215, that's how Roger's engineers designed the system. Result will be that first floor will heat a little faster and will be a little less short burner cycling. An original inquiry was "is this normal?" Answer is mostly yes, but I just outlined how to minimize short burner cycling. It is not a big deal, your fuel usage is at a minimum with an EK boiler properly set up. Consult your EK digital manager guide for proper dip switch setting, I don't remember offhand.
Re: Indirect HW off steam- shaking circulator
While not a cheap date, this type of circulator, a B&G PL series, would keep the motor out of any dirty water. This is an air cooled motor as opposed to a wet rotor design., 225°f rated
The B&G series 100 is another option.

Re: Water heater as buffer tank
This is the control I like to use. It has a lot of adjustability, nice readout. Other versions from HW and Johnson controls. The sensor against the metal tank jammed under the tank foam insulation is accurate enough.

Re: How well is my heating working at lower water temps?
As was mentioned earlier, it is difficult to dial in the fan coils with modulating input boilers. Especiall;y with the outdoor reset feature. The fact that you have a boiler that will modulate supply water temperature based on the outdoor temperature should eliminate any on off cycling of the boiler once the outdoor temperature drops below the boiler’s turndown ratio minimum input requirement. As the outdoor temperature drops the boiler should increase in temperature to the fan coil that runs constantly. Best if there is an air handler with a variable speed fan to adjust the fan speed as the outdoor temperature changes. Thus it will have a fan that never stops (just changes speed) and a boiler input that constantly adjusts the water temperature to the fan coils based on the outdoor temperature.
Since there are no controls for that particular combination of equipment currently on the market for general use, You will probably never get the efficiency you might expect from a radiant floor system or cast iron radiator system. That said, the combi has resulted in lower fuel usage from the original “on/off” boiler system from years ago. I have a feeling that you are going to keep adjusting for some time, Until you have a real issue to resolve like a daughter getting married or a parent going to the nursing home. That usually takes focus away from heating systems. Even for the engineer types.
