I’ve lived in multi family wood homes in the US without issue. It can be an issue with the cheapest construction, but sound insulation can mitigate or solve those problems.

Since moving to Boston I have only lived in multi-family wooden houses, and this just isn't true, at least with modern-ish insulation. I can occasionally hear my upstairs neighbor's dog when she gets excited, and precisely nothing else.

Hm. The only multi-family building I've ever lived in was an apartment complex and it was steel and concrete. I don't think they are typically built out of wood even here, although I've read about some experiments with wooden office buildings as more environmentally friendly. I guess if I was really curious I could look and see if they'd added extra sound damping to deal with that.

In any case, the typical American wooden home is not going to have a family above you. :)
