Modern air or ground source heat pumps tend to be quiet, even silent, at least according to some deep dives down the Youtube rabbit hole on passive houses. Check out the "Moonstone house" on Youtube for example.
However, the house is new, let's see how it the unit sounds in 5-10 years.
That being said, do yourself a favor and do not get a heat pump connected to 'the cloud'. Our heat pump can't be fully controlled locally (some functionality is web only) otherwise I'd put it offline. They unnecessarily performed repairs on the heat pump to the tune of 500€ because their servers had issues.
