ᐅ Cooling via underfloor heating with a ground-source heat pump

SirSydomHello everyone,
I am very sensitive to heat, so this will be a major focus in our new build.
In addition to an automatic shading system with venetian blinds and roller shutters, and a solid construction method, as well as a ventilation system with a bypass (and possibly a ground heat exchanger), I am considering whether "passive" or "free" cooling through the underfloor heating system makes sense. This is said to have only low operating costs since only electricity for the pumps is required. The technology also seems quite simple—a heat exchanger between the brine circuit and the underfloor heating circuit, possibly with a few valves and a mixer.
Now I am wondering if the effort is worthwhile—does it really make a difference? Does anyone have a direct comparison in the same house, once with and once without?
My wife is still quite hesitant because she fears having cold feet. "In summer, I want to walk barefoot." Is this concern justified?
Are there alternatives for cooling that won’t immediately break the budget? A separate cooling ceiling would certainly cost several thousand euros.
With a conventional split air conditioning unit, I can already hear my wife complaining about drafts, so that option is probably off the table.

1) Passive cooling. This method dissipates a small portion of the heat through the brine without using compressor technology. It costs around 2,000 EUR more for the equipment.
2) Active cooling. This works even in the Sahara and operates like the back of a refrigerator with a compressor. It is significantly more expensive.
