ᐅ Structural engineer according to HOAI or fixed-price offer?

Good evening, we are about to commission a structural engineer for the following project:
New construction of a semi-detached house hälfte (--> half!), without a basement, 140 sqm (1507 sq ft). Structurally "not quite simple," according to the architects.
We have now received an offer from the structural engineer for 28,000 EUR for service phases 1–6. According to the HOAI calculator, this corresponds appropriately to the eligible costs.
Nevertheless, this fee is quite high – two questions:
a) Should we look for a fixed-price offer (possibly from another structural engineer)?
b) Does a “more expensive” structural engineer ideally provide smarter solutions, for example by avoiding the need to fill the entire ground floor with support columns?
Thank you!

Exactly these points or the absence of stacked walls are the main cost drivers… Yes, but we don’t know if these details even apply to the original poster ;-).
That’s why my question…

"Structurally not entirely simple" could describe our project due to the following conditions:
- The plot has sandy soil (although a semi-detached house was previously built there, so it is pre-compacted).
- The floor plan includes an open space/gallery from the ground floor through the upper floor up to the attic.
- Most of the interior walls do not align vertically.
- Yes, a smaller corner glass window is planned on the ground floor.
- A larger dormer with a small balcony is planned.
We have now requested offers from other structural engineers for comparison, and I am curious to see the results.

Hopefully, the open space up to the roof isn’t located in the living room.
If possible, interior walls should be aligned vertically.
Corner glass windows are outdated nowadays.
Is the large dormer approved by the building permit/planning permission?
Is this design from the architect?

I could also provide you with a quote.
Which federal state is it?
