ᐅ Lightweight concrete with infill? The dilemma of choosing the right masonry system

Hello,
we are planning to build a new single-family house and are currently in the selection phase regarding the type of block.
Our current favorite is the Liapor SL Plus with a thickness of 36.5 cm (14.4 inches).
However, since this block is not commonly used in our area (Saarland), our research so far has shown that it is sold at a relatively high price and that few masons have experience working with it.
Some masons / construction managers have also advised against blocks with filler, as they are said to be less or not at all vapor permeable, which could cause moisture to move from the filler inward over time, resulting in stains on plaster or wallpaper. This seems rather far-fetched to me?!
Besides thermal insulation, we also place great importance on soundproofing, but we definitely want to build monolithically—so no external thermal insulation composite systems (ETICS) / external wall insulation.
What other options do we have in this regard?
Aerated concrete seems to be ruled out.
Clay blocks (Poroton) are probably problematic when it comes to drilling holes and fixing things.
We would very much appreciate any suggestions on this topic.
Best regards

In comparison, the 232 is an absolute quiet performer.
Quote from a railway construction contractor:
"A Ludmilla never had to be announced by the signal post before. It took care of that itself!"
Only GTW2/6 trains and occasionally a diverted train pass through our area. The last time, about three weeks ago at 11 p.m., was a Ludmilla with a handful of loaded freight cars.
The sound of the Kolomna engine combined with the turbocharger and generator is unmistakable.
Still, it was quieter inside the house than when flushing the toilet.
And since the original poster wants to build in a 30 km/h (18.6 mph) zone, the type of brick used is unlikely to have a noticeable effect on the noise level inside the house, or I assume they would neither be able to identify nor locate the sources of noise.

Yes, the 5D49 old ventilated models were really cool. For a while, they even used a 242 and later a V330 (Blue Tiger by Adtranz) in traction. The 330 was almost as loud as the original Ludmilla!
If the toilet flush is louder than a passing 12D49, then the plumber must have been a bit careless! Except for the guest bathroom, I can’t hear my toilet flushing anywhere in the house (timber frame construction).
So, for the original poster: with decentralized ventilation, the house will always be a bit noisier, but otherwise you can confidently use aerated concrete for the exterior walls. For the interior, I would actually lean towards calcium silicate bricks.

...If the toilet flush button is louder than a passing 12D49, then the plumber also messed up!... No, he didn’t. First, the unit was not operating at full load, and second, I was referring to noise levels that are lower in intensity than the emissions from a standalone refrigerator compressor measured at 1 meter (3 feet) distance.
The attenuation through masonry and windows is higher in this case than through the door to the bathroom.
