I got a Vent axia 'Centrif 250' 100mm fan for my kitchen in my
previous house.
Noisy, but powerful. I was selling the place, otherwise I'd have been
really disappointed in the level of noise from the thing.

Centrifugal fans are always noisy. You are trading performance for noise.

Generally, a 100mm fan is too small for a kitchen anyway - far better
to use a larger axial model and a 100mm axial model for a bathroom.
