We are currently planning a single-family house.
I am undecided about a concrete cistern (concrete for durability).
The plot is about 800 m² (8600 sq ft). The cistern is intended for garden irrigation (although not much will be cultivated in the garden). How large should the cistern be at a minimum?
What costs should I expect?
Is the investment worthwhile?
How is the water withdrawn? Can the cistern be connected to the outdoor tap?

No idea, since this is an existing property.
However, you won’t be able to compare anyway: type of cistern, size, technology (filters, etc.), piping, electrical connections, soil conditions, construction stage, delivery...
If the large excavator is still there, it might be able to dig a hole and install the cistern quickly with just a few scoops. If the house is already built and a mini-excavator and lifting crane are needed, the effort is much greater.

Here is a recent offer from North Rhine-Westphalia:
Concrete cistern approx. 3.1 m³ (110 ft³), up to 3.50 m (11.5 ft) away from the building, including piping and backfilling with connection to the roof drainage system: €3,754.00. If the cistern is to be connected to the toilet flushing system, an additional €1,936.00 applies for 2x toilet flushing lines (separate piping), an outdoor tap, and fine filter including pump.
For Baden-Württemberg, you can expect costs about 4-6% higher.
Best regards, Bauexperte

What did you pay for the cistern (concrete or plastic?) Including installation?

Concrete cistern approx. 3.1 m3 (110 cu ft), up to 3.50 m (11.5 ft) away from the building including piping and backfilling with connection to the roof drainage: €3,754.00. If you can get exempted from wastewater charges for the outdoor faucet, you end up paying more in interest on the €3,754 than you would save on water costs for 25 m3 (882 cu ft). Even if you can’t get exempted from wastewater fees, the cistern only pays off after 25 to 30 years assuming an interest rate of 2.5% and a water price increase of 1.5% according to Destatis.de—provided the cistern never runs dry (which I doubt with 3.1 m3) and no additional repairs are needed (pump, etc.).
Would anyone really choose to install this on their property voluntarily if it’s not required by the municipality?
