Which windows are installed, how well are they insulated (if you know)? Does the house have balconies or other cooling fins / thermal bridges?
Is the roof insulated?
It might make sense to go through everything with an energy consultant, which doesn’t cost a fortune in the first step and they can advise you more expertly.
When deciding for/against a heat pump, I would also consider how you assess the forecast for heating costs in the coming years. Everyone sees that a bit differently. We decided (in the new building, however) for a heat pump because we expect that energy costs will rise (both for electricity and gas), and that CO2 will be taxed so heavily in the coming years that gas prices will diverge significantly from electricity prices. But that is just our personal forecast; of course, nobody has a crystal ball.
In old houses, there is also a good synergy with photovoltaic systems when using heat pumps. You might want to plan some budget for that. A system without storage usually pays for itself in under 10 years.
And then there’s the ideological factor. I personally would already not install a gas heating system out of conviction. I have 2 children. ;)
We even switched to an electric car with a weekly mileage of maybe 100 km. That’s barely economically justifiable, but we didn’t want to keep burning dead dinosaurs. =) But that’s also a personal assessment, just a food for thought on how you feel about it.
