Heat pump sure, but how is gas furnace more efficient than resistive load inside the house? Do you mean more economical rather than more efficient (due to gas being much cheaper/unit of energy)?

Depends where your electricity comes from. If you're burning fossil fuels to make electricity, that's only about 40% efficient, so you need to burn 2.5x as much fuel to get the same amount of heat into the house.
Sure. That has nothing to do with the efficiency of your system though. As far as you are concerned this is about your electricity consumption for the home server vs gas consumption. In that sense resistive heat inside the home is 100% efficient compared to gas furnace; the fuel cost might be lower on the latter.
Sure, it's "equally efficient" if you ignore the inefficient thing that is done outside where you draw the system box, directly in proportion to how much you do it.
Heating my house with a giant diesel-powered radiant heater from across the street is infinitely efficient, too, since I use no power in my house.

It’d be fun to actually calculate this efficiency. My local power is mostly nuclear so I wonder how that works out.
You accelerate the climate catastrophe so there's less need for heating in the long run.
