ᐅ Electrical installation too expensive – oversized or just overpriced?

Hello everyone,
We received the quotation for the electrical installation, and I had to sit down first.
So far, everything has roughly matched the values found online (excavation, surveying, structural engineering, architect fees, etc.), but the electrical installation is about twice as expensive as what is generally indicated on the internet: €23,000, while we had planned for €10,000–12,000.
On closer inspection, we noticed that the quotation seems oversized and appears to cover all possible contingencies. The final billing is based on actual usage, so I would like to get your opinion on how over-dimensioned it really is. The prices include installation.
A few items can be deducted or reduced considerably. (For example, I do not need 17 temperature controllers with displays at €100 each), which would save about €1,000 right away. Also, a network cabinet with a patch panel listed at €400 can be found for about half that price. Having 110 sockets plus 10 Schuko sockets also seems excessive to me.
There are also elements included that I have not seen elsewhere: all installations (kitchen, heating, garage), roller shutter control and connection, ventilation installation, mailbox with intercom system. Still, I cannot get the total below €15,000, let alone €10,000.
Here are my top 10 items – is this very oversized? Or am I unlikely to save much? Especially the cable lengths are about double what I see online.
Room temperature controller €104.12, 17 pcs, €1,770.04
Sheathed cable 5*1.5 mm², €1.83 per meter, 700 m, €1,281.00
Socket outlet Jung AS520, €9.25, 110 pcs, €1,017.50
Meter cabinet €856.34, 1 pc, €856.34
Sheathed cable 3*1.5 mm², €1.41 per meter, 600 m, €846.00
Mailbox system with intercom €568.49, 1 pc, €568.49
Electronic transformer €29.43, 14 pcs, €412.02
Silicone protective cap €26.10, 14 pcs, €365.40
FR bathroom light €58.38, 6 pcs, €350.28
Residual current circuit breaker €68.26, 5 pcs, €341.30
Roller shutter: programming €338.71, 1 pc, €338.71

Pure convenience and aesthetics seem like more relevant reasons to me.

Safety is also an important consideration because multiple power strips that are left lying around can quickly become dirty or exposed to moisture, especially in a child's room. I once saw one smoldering. It definitely could have caught fire without a fuse being triggered. Fortunately, I noticed it in time.

Dusting off the parts should also be mandatory.

I also think pure convenience and aesthetics are the more relevant arguments here.Exactly, how often do you really push 16A continuously in a single room? Short-term, you can easily have 5 kW or more running.
