How does engineered wood do on strength and fire resistance? Would appreciate any unbiased comparisons vs. steel and concrete on those points

That is something I've wondered too. I imagine foundations, elevator shafts and other key parts might still be concrete. Buildings like this are fascinating: https://www.dezeen.com/2019/03/19/mjostarne-worlds-tallest-t...

Elevator shafts can be made with CLT too, like for the 9 storey Murray Grove in London built in 2009

Burned wood acts as insulation for the unburned core so large timbers can have long fire ratings. The rule of thumb is 1.5" per hour. [0]

I can’t comment on reinforced concrete, but structural steel requires protection to meet 1+ hour fire ratings.
