Concrete or brick buildings are much nicer to live in, but expensive, so they are not very common among new constructions.

That said, plenty of steel-framed apartments are effectively sound-proof. I’ve lived in them. You don’t need masonry, just wall mass.
Masonry can be engineered to US seismic standards but it is extremely uneconomical to do so. In my city, my house must be engineered to survive without structural damage an earthquake stronger than any in European recorded history. That’s not over-engineering, large parts of the US just have earthquakes that strong. It limits your material choices.
Similarly, US construction must also be engineered for extreme wind loading. Some of the buildings in my area are designed to withstand 300+ km/hr winds. Because that is a thing that can happen here.
Just about everything about US construction style can be explained by the necessity of engineering to survive extreme seismic and/or wind loading. Which it demonstrably does for the most part.
Once you start moving out of the dense parts of Tokyo, wood construction becomes a lot more prevalent for the same reason: it’s cheaper to build a stick house to code than it is to hire RC specialists.
It’s also quite expensive.
Normal Japanese construction has always been wood frame.
Some recent skyscrapers in severe seismic zones don't use conventional reinforced concrete. Their cores are built from welded steel plates, between which they pour concrete. It is much less labor-intensive and purportedly has excellent seismic properties.
I've lived in pretty large buildings (eg dozens of units and four floors high) that were largely made of wood in both the northeast of the US and California.
They aren't high-rise buildings but I wouldn't argue they aren't apartment buildings, and they're far from uncommon.
It’s called a 5-over-1 and it’s so much cheaper than doing five stories of metal pan and concrete deck that the economics force the decision. You see these everywhere.

Anything over 6 stories will be concrete and steel, or rarely, engineered wood or timber framed.
Concrete and steel apartment buildings do not have vertical concrete partitions or wood stud walls between the units, they have steel stud walls with two layers of double 5/8” drywall on each side to provide a 4-hour fire rating.
I am a construction professional, FWIW.
