Basement originally partially concrete, now possibly completely brick-built

soil is known through neighboring plots

With all due respect, that is nonsense! The soil on a property can be completely different. It’s not for nothing that most structural engineers require a soil report; otherwise, a foundation on the patch of earth where the house is supposed to go can’t function properly. But better to save 800 euros now...

I want to prepare for the conversation about the cellar and not show up there with just partial knowledge, but at least with half knowledge.

you won’t be able to acquire even 10% knowledge in such a short time.

Hollow clay bricks with a thickness of 42cm are now planned.

Can one also draw a conclusion about the watertightness from the thickness of the bricks, or is it generally assumed that masonry walls have poor to no watertightness, so that all measures must be 100% carried out through the bitumen layer?

The thickness of the stones has nothing to do with the tightness. Even a 1 m thick concrete wall will let water in at the construction joints if no appropriate sealing (joint tapes, etc.) is provided.

Hi, In previous discussions and offers, we have so far agreed with our provider (architect/owner of the construction company (=own yard, excavator, employees, etc.)) to build the basement roughly half out of 24cm thick concrete and the other half by masonry. (...) Back to the upcoming architect meeting. Should he guarantee the tightness to me in writing? A concrete variant is definitely watertight and generally requires less of a lengthy guarantee.

WU concrete is only impermeable to liquid water but always allows water vapor to pass through. Keyword: Schnappsglas formula (1 glass / m2 / day). The water must be ventilated away.

No - water-impermeable and impermeable to liquid water is a world of difference! See #post 10 ;)
