ᐅ Sand-lime brick or autoclaved aerated concrete (AAC) blocks for house construction – how to decide?

Anna_BWHello dear forum,
We are now in the final stages of planning. The next step is choosing the building blocks. We are constructing a city villa with an attached bungalow. The plot is located next to a tram track (with a narrow street in a 30 km/h (about 20 mph) zone in between), and behind that there is a fairly busy road. A new school center is currently being built about 200 meters (220 yards) away as the crow flies.
The options are:
1. Ytong PP2 with a U-value of 0.23 W/m²K (0.04 Btu/(h·ft²·°F)) or
2. Sand-lime brick 17.5 cm (7 inches) with 1600 mm (63 inches) mineral external wall insulation system (EWIS)
The financial difference between the two systems is not decisive. I know there are strong opinions here about which system is best.
My main concern is noise insulation. I would consider myself sensitive to noise and am worried that choosing Ytong might turn out to be a mistake.
Are there any experiences? Decisions that were right? Decisions that were wrong? Or insights that could guide me in any direction? The choice of block will be a joint decision, although I am probably the only one leaning towards sand-lime brick because of noise protection.
Thank you very much!

2. 17.5 cm (7 inches) calcium silicate block with 160 mm (6.3 inches) mineral-based external thermal insulation systemWhat is the wall thickness of the Ytong? You might lose a few square meters there, which could factor into the decision. We are building with aerated concrete and, for example, separate the granny flat using calcium silicate blocks.
