Just to add to your points, all of those are already a thing in colder climates. Google DC in Finland is one example. When it’s heavily below zero half of the year it’s just not possible to run open loop systems and there’s plenty of use for the excess heat. Some DCs just donate the waste heat to municipal heating. PR obviously plays role in that, but that’s easy way to get rid of the heat and datacenters don’t need to manage the heating network and fluctuations on demand, so they also benefit from someone who’ll just take the heat away from their ‘hands’. Also sound is automatically better managed since you need decent insulation on the buildings to avoid condensation and other problems which come when temperature differences are pretty huge between inside and outside of the building.
Heat exchangers and/or heat pumps to move energy to water and then pump that to district heating network which then takes care of heating of all kinds of buildings.

How do you donate heat? Ventilation pipes?
