For our single-family house, the Poroton FZ8 brick from Schlagmann will be used, combined with mineral wool insulation to achieve KfW 55 energy efficiency.
I am now uncertain if this is a good choice, since these bricks are designed for commercial buildings and not specifically for single-family houses.
Can you help alleviate my concerns?

I’m missing the knowledge about when to refer to buildings as commercial projects. The term "commercial orders" is used in industries like flooring or furniture trade when someone orders a hectare of needle felt or containers full of stackable chairs—basically, when an order volume approaches a full day’s production. For this sales channel, there are special, more durable quality standards. In your case, “buildings” could mean school complexes, hospitals, apartment blocks, or similar structures. Your stone probably crumbles less, absorbs mortar better, or wears down saw blades less. For example, there are stones or wall elements that measure 60 cm (24 inches) instead of 50 cm (20 inches) in length because commercial construction uses different modular dimensions. Your contractor might even be using the same stones from the central warehouse for single-family homes as for high-rise buildings. “Nothing to be afraid of,” as the hero would say ;-)
