thanks for the opinions, these are views that actually help me.
After my further research here in the forum, the building savings contract is also seen somewhat critically (so it doesn’t have many fans)

You yourself have now said several times that you want security, right?
Security has absolutely nothing to do with whether it is cheaper or more expensive at the start of construction than today, but exclusively that you already know the interest rate today. And that leads to the actual core of security, namely to keep the installment always the same, or to know when which installment has to be paid, so that you don’t suddenly have a higher burden.
And that works very well with a building savings account. On the one hand for the loan (60%), on the other hand also in the saving phase, because with it you can significantly shorten the first fixed interest period. For example, you only need 7 years until the building savings contract matures, so you can choose a fixed interest period of 7 years for which the interest rate is significantly lower than for the 10 or 15 year period.
To make the monthly burden lower, look for a building savings contract with 30% minimum savings and 4 per mille repayment rate. With the remaining available installment you can repay the remaining loans (KfW and bank) faster and thus also increase security again, because the less residual debt in the uncertain components, the better.
And yes, absolutely correct, this is not the cheapest model. Far from it. But if you want security, then this can help you.
