About 4 years ago I had a Goodman dual fuel heat pump/furnace installed . It is an 18 SEER with LP furnace . It is a conventional heat pump vs inverter . Here in north Georgia it is a good way to go .

At 39 degrees or colder the LP furnace is used . Above 40 the heat pump is used . The unit we replaced was also a dual fuel but only 10 SEER . Our electric bill dropped like a rock with the newer unit . I have no complaints .

In my 24 x 26 man cave garage with 12 ' ceiling height I have a 24k Mitsubishi mini split that is 24 SEER . That unit is VERY efficient and I have yet to have a cold temperature where it didn't produce heat . But the coldest we have seen was about 20 degrees . On the flip side we have seen 100 degrees in the summer and it cools great .

If I was ever to build a house I would specifically build with mini split in mind . A single outside unit can run multiple indoor heads . I think that may be the most efficient way to heat/cool without going Geothermal or similar .
