In my experience concrete can act as an amplifier, just as much as wood frame can dampen sound. Just wait until your upstairs neighbor decides to install wood floors and take up what sounds like flamenco bowling and you'll realize that you need about 4 feet of concrete to not hear them.

Not really. I worked on during construction, worked in (my office), and lived in buildings with, approximately, 6" of concrete floors and there is very little sound travel unless you are really banging away - and I've never heard any "amplification" by concrete (I don't think that's actually possible) - it can conduct sound though, but the sound weakens with respect to distance. Sure, if you live in a wide open loft that has exposed brick walls, ceilings, duct work, etc. then your own voice will echo and reverberate enough at frequencies that can travel through adjacent units via thin walls and the duct work, but typically most people furnish their spaces with artwork, carpets and/or rugs, beds, furniture, etc. all of which dampen and absorb soundwaves. All bets are off if someone really cranks things up with a loud stereo or dozens of people in a party, but concrete will always outperform timber when it comes to soundproofing between floors. Let alone it will be physically stronger during weather events. A person is doomed when they get hit with even a small tornado or a fire in these 5-6 story stick structures. Scary and unsafe, IMO.
I have also lived in an apartment with bare hardwood flooring between units and that was awful for noise transmission - though the space itself was nice. High heels, kids tapping, playing with marbles, creaks from movement, almost any kind of TV or music, all that activity transferred through the floor much more with hardwood than with bare concrete. I also grew up in a 70s-built apartments, these were carpeted. Again, it was an uncomfortable and unpleasant experience.
When it comes to structures with concrete floors, the weak points are, as you mentioned, walls, and of course windows. Some walls are better than others. Having lived at Sherman Tower and Pennwood Place (concrete floors, drywall for common walls) I almost never heard anyone except for a guy who liked to go out on the balcony and scream bloody murder at 3:00 am once in awhile. Also, if someone has a loud boomer party, that sound will travel. Bass travels well in almost any situation.
These stick buildings are not such a bad product for young people who are trying to get off the ground, but the rent / purchase rates are so incredibly high for such crappy product. I don't see these as a real positive investment opportunity for people. Some may do better than others depending on location and construction quality, regardless of stick-built or not.
Speaking of which, the monstrosity of timber across from Moe's Bagels is... well, I think it's a little monolithic. That thing is huge. All timber above the first floor.
The reality is, the Denver market is overpriced given the cost of living, wage rates, and product quality. I realize it's dictated by demand, but it doesn't mean the price is worth it.
This issue is also fueling a whole other problem. Fewer people can afford to live in their own studio or 1-bedroom. Now, there are single-family homes that are being occupied by several sub-renters of bedrooms. It's happened to me next door. My HOA or Douglas County can't do anything about it even though it violates the Zoning Code. It sucks.
