I haven't read or watched anything on terraforming Venus in a long time, but isn't a large part of the challenge not just temperature, but the sheer mass of the atmosphere? As in, even if we could cool it, wouldn't that bury the surface under hundreds of meters of dry ice?

Yes. That’s not really a challenge through as it would freeze from the bottom up, unlike water. What is difficult is that it would need to be covered in some sort of insulating material on a global scale before the planet is ever warmed up. The outgassing CO2 could be captured and turned into carbon and oxygen, with the carbon put to industrial use or into biomass and the oxygen feeding a 400 millibar O2 atmosphere in settlements. But a sudden volcanic triggered burst of CO2 would be a forever ongoing global risk.
