Which POROTON variant should you choose?

Unfortunately, not even the Poroton image brochure states which of the possible variants one should choose.

Planned is a 230 sqm single-family bungalow with a gable roof in Northern Germany. So with a brick facing facade.

Now there are Poroton bricks with unfilled holes, with perlite filling, and with mineral fiber filling.
These can also be optimized for thermal insulation or sound insulation.

Leaving aside the different thermal conductivities, when do you choose which brick without or with filling for a cavity wall house?
Is the different filling just a question of price (is there even a difference) or is it a matter of belief? Or do the different filling materials have different properties?

Only in case you have not already found an answer: The filled bricks (Poroton is just one brand among many on the market) are usually used for a single-layer wall structure (except for T9 unfilled). The other unfilled bricks (usually of rather low thickness) are then used in double-layer wall structures when an insulation layer between the two layers performs its function. Clear so far?

Sound insulation is more of an issue for multi-family houses. For single-family houses, it is not needed excessively.
