It often is... but that is mostly driven by cost of construction rather than the inherent capabilities of wood. The owner decides what level of performance they are willing to pay for, based on what they feel the project can afford.
You can do better acoustic isolation (with specific wall and floor assemblies) in wood than what is typical, but it costs more and developers/owners of rental properties are most often not willing to pay for that, because they are building out of wood to stay affordable.
Architects always provide the owner their recommended options to mitigate acoustic transfer based on both past experience and what the project's acoustical engineering consultant determines after reviewing the drawings.
Cross-Lam timber construction turns this on its head. It is NOT cheap, and it is completely different acoustically. A far more 'resolute' construction method. I'm excited to see how economically viable the method is, here. If it slots in below concrete and above stick frame, you'll see it take off if the jurisdictions it's proposed in, allow it.
