I have family in Switzerland and have asked similar questions, so this is what I have found...
Farmhouses tend to stay in the same family.
My family's home isn't timber, was bought via an agent although its a weird living set up with the neighbours who owned the entire complex at one point. Odd people, when I last stayed over, I had a very heavy period and apparently they went through my rubbish to ensure I was putting recycling where it should be. Apparently they got a real shock when they opened one of my ''parcels''...
Their snowfield chalet was timber and that was bought and sold via a normal agent who specialised in that area's real estate.
The cheaper social housing blocks being built look like concrete boxes and apparently upset a number of the population.
Farm land fencing is usually temporary electric tape/cord moved daily. My Family's residence has hedges on the boundaries but the dog lives indoors and only goes out when a family member goes for a walk, which is very common and several times a day.
Cars are registered in the canton (district) where the owner lives, and the registration fee etc is based on the Canton's social economic environment, so for instance Lucerne is a relatively expensive place to live, so their registration fees are more expensive than say Bern. You can tell where a car comes from as the numberplate has an abbreviation on it for that Canton.
My family shop over the border in Germany. I have been with them, never saw a border manned but always advised to take my travel documents. Food is imported into Switzerland, some of the produce was grown where I live, and I thought considering the distance travelled, wasn't too bad in price. Meat is expensive though...
Everyone generally is polite, helpful although can be distant. Multi-lingual.
The self employed relatives carried on travelling during COVID and also continued with overseas holidays, just undertaking RAT tests before we ever saw any in our country. They have now all had 4 jabs.
Most cantons have mixed property types. In my family's one, they have residential housing, forestry, farmland and a big recycling centre, in the township some horses are kept in open stables and its all just accepted as is, no ''not in my backyard'' attitudes.
My Family's shelter stores their wine harvest! The main one nearby is locked (which I couldn't figure out who would have the time to unlock it in case of need) but stunk of urine and old cigerettes, so potentially not as clean and looked after as it should be.
Zurich train station never has enough euros in the ATM machine so make sure you have plenty if catching a train into Italy for example...
