I think this is going to depend somewhat on how congested your area is, but Starlink is my home ISP and I sometimes get faster (download) speeds at home than I do at the office where we have fiber at 200 Mbps down. It has a little more variance but is consistently quite fast. If the backend is on GCP, it amazes me how fast it will go.
Why does your office only have fibre at 200Mbps down? Last office I was involved in setting up, we didn’t need symmetrical gigabit but the cost was fairly inconsequential compared to lower speeds, so we just went with the gigabit… Really strange that service providers even bother running fibre at lower speeds for commercial accounts…
