You may want it but you wont get it even if they say your speed is 1Gbps.
No server will be able to send and receive at 1gbps unless you are the only one interrogating the server and it has multi gbps connections to the internet backbone. Addtionally there are probably several servers between the server hosting the interrogated website and you.
As I already said, with modern CDNs, it's quite possible for there to be a clear, unbottlenecked 1Gb link between you and the bulk of data you are downloading, which will be stored on a whole bunch of servers with 10Gb connectivity to a 10Gb (or faster) backbone.
You don't need a "dedicated" 1Gb link to saturate for major benefits, either. just being able to burst up to a Gb for second or so at a time delivers huge perceived benefit, but dozens of people can do that on average across a single 1Gb shared upstream over a reasonable period of time (10s of seconds to minutes).
Exhibit A.
Say you have netflix account and want to watch netflix 4k (on 4 separate TV as you can get 4 subaccounts I think) you will only need 100mbps. what else are you going to need the other 0.9gbps for? You probably will need a "marketed" 1gbps connection and will prob in actual real world only get sustained 100mbps. who knows. Be prepared to pay lots. Not because the the fibre can carry much more but the internet backhauler will have to lease multi gbps links across the southern cross cable. Current capaciy across Southern cross cable is 7.4 Tbps. Thats 7400 Gbps. Theoretical capacity is 22Tbps (at the moment).
Your premise is flawed. You don't need to go overseas for your content. In most cases it's cached locally and your requests probably won't go any further than your nearest capital city.
