I would not go with an air to air HP in N.D. If you can wait, I would install a split geo-thermal system.

I hadn't really thought about a geothermal system. I'll likely call my utility company to see if there are any local installers. The nearest ones I can find online or in the phone book aren't very close.
In the year that we've owned the house, our propane cost (includes hot water heater) averaged $95/mo and the electric was $80/mo. I plan to replace our current water heater with a Marathon model if/when we get rural water installed. I'll likely hook that up to our electric company's off-peak program. If I do that, rates will be $0.044 per KWH with a $5/mo controller charge.
I guess I just need to get a quote and see what the payback time frame looks like.
I screwed up and hit the wrong button and my last comments went to "la..la.." land. But I was just guessing that you will probably have a heat pump with a 2nd stage heat with propane or natural gas? I thought N.D. got colder than what a heat pump can effectively heat. Maybe not. 45 degrees is a pretty warm winter, perhaps I should consider moving to N.D.
I think it's a very good idea to get as much efficiency as you can. So a 2 stage compressor, highest seer you can afford, variable speed fans and any bells and whistles that you can afford. The Wi-Fi T-stat may be unnecessary but it's something I would like.
I can't really suggest any particular brands. I'm more in industrial service and not so much involved with residential but I'm grateful for the research you've done since I'm trying to decide which unit I should buy when I finally replace my hvac that I've had since 1977. Good luck.
In most areas the payback time on high end equipment exceeds it's lifespan. You go to 15 SEER for energy savings, the 2 stage stuff is more for comfort than saving money on utility bills. 2 stage equipment is almost always oversized, killing any real world savings that would have been achieved by the higher SEER ratings.
How about a Carrier Greenspeed Heat pump, but not hybrid heat... just all electric? Nice long cold winters is SD, might have a descent payback. IT will definitly add comfort with long run times all year.
That coil isn't an approved match with any of the heat pump models you were quoted. Ask your dealer to provide you with the AHRI reference number for the system he plans on installing. Here are some system matches using the CX34 coil:
