ᐅ Exhaust air and outdoor air heat pump or ground source heat pump, timber house, heating system

BajuwareHello everyone!
My family and I are planning to build a house, and it is almost decided that it will be a wooden house.
Regarding the heating system, we are now considering whether to install an exhaust and outdoor air heat pump or a ground source heat pump. The construction company responsible for completing the building recommends a ground source heat pump. One reason is that an outdoor air heat pump only works effectively down to about minus 7 degrees Celsius (19°F) and below that temperature requires an electric heating element, which consumes a lot of electricity. Another reason is that the construction company has a partner who can carry out the deep drilling for the ground source heat pump at a favorable cost.
However, I received information from another builder that an exhaust and outdoor air heat pump can use excess heat produced by a wood-burning or pellet stove in the living room to warm the heating water for other rooms, which can further reduce energy consumption.
Since this house is an investment for the future and will eventually be our retirement home, I want to invest in a system that is as future-proof and cost-effective as possible.
However, I am not completely clear on the differences between the two technologies or their advantages and disadvantages, and so far, no one has been able to explain it in a way that would allow me to make an informed decision.
I hope you can help me here, and if this topic already exists and I have overlooked it during my search, I apologize.
Thank you in advance for valuable tips and clear explanations for a layperson.

Hello,
It seems this was probably neglected here, as is often the case.
Ask 10 more companies and you will get 10 more opinions! ;-)
Best regards

...The construction company, which finishes the building ready for occupancy, recommends a ground-source heat pump.... and partly because the builder has a partner who can carry out the deep drilling for the ground-source heat pump at a favorable cost.
