Also remember that past about 150mbps you are not going to utilize those speeds unless you have several devices pulling data at once, like multiable TVs streaming 4k content When I worked at an ISP my desktop had a full 10Gbps connection to the internet (for testing), and user experience was not any different than the 100Mbps I had at home. Most services will not serve you data at more than a few megabits a second, even big cloud services.
