If you what to get quite fancy, modern OEMs use a heat pump run with a
small variable frequency drive. About 4x the efficiency of a resistive
heater. No joke, and that is a serious increase in range in the winter.
No doubt, you can get a Leaf compressor cheap in the bone yard.
By adding the proper valving, you have the bonus of air conditioning,
but that is even more of a project. The good thing is, you can reuse the
cars existing air conditioning condensor and evaporator and some of the
A/C plumbing.
It can get quite complicated, however, and a resistive ceramic type
heater core is, no doubt, the simplest option. I'd opt for a "high/low"
switch (series-parallel?) on two ceramic heaters, or some sort of
thermostat on the outgoing air from the heater(s).

Respectfully, when I did Civicwithacord, the goal was defrosting the windshield
effectively, not keeping me warm. Yanking out the dash to install the ceramic
heater in the old fluid core housing was easily the biggest b---h of the
conversion, but the time and look and safety was well worth it!!

I used a 1500W heater core in my Geo Metro conversion, and I'd say that it
kept the car kinda "warmish" on really cold days. But I think if I'd taken
the time to put extra insulation in the car, that would have helped.
