Ceiling fans meaningful?

Can someone tell me when ceiling fans make sense and when they don’t?

My large living space is 55m². The ceiling is lowest at the windows with about 2.3m, in the middle it is about 3.3m, and up to the ridge beam almost 4m ceiling height.
These are quite decent measurements for a ceiling, and since heat is known to rise upwards, I have to heat a lot for the room to stay warm or be warm.

Now I thought about installing ceiling fans so that the warm air hanging at the ceiling is pushed back down. Of course, in summer it should also provide some cooling.

Personally, I only know normal stand fans, which are on the one hand loud and the airflow you feel when blown on I find unpleasant.

Since the room is shaped like an "L," I am thinking of 3 fans. The three areas then have about 18m² each. That way, each section, living, dining and kitchen, would have its own fan.
Would that make sense?

Do you feel a draft from the fans or hear them?
How do you size these things?
What power consumption must I expect?

Basically, it’s probably enough if the fan runs on the lowest setting; especially in winter the air should just be circulated.

But I don’t want to feel any drafts, and if I come out of the shower naked and lie on the couch and then fall asleep, I don’t want to wake up sick, just to mention an extreme example that should not happen.
It should simply be so that it doesn’t feel like sitting in a windy spot.

I hope someone here knows a bit more about this.

Good question... I'll join in, even though I only have 2.5m standard ceilings. But above the couch in summer, we had also considered it.

I do have a ceiling fan in mind by now, but I would like to control it depending on the temperature. It seems to me that this is not just available as a standard. Usually only some unattractive industrial solutions. But I do not want to install those in the living area. I also wanted to save myself from building a controller myself...
