Unless you are routinely downloading large files and have appropriate multi-gigabit network interfaces, 1gbps (or even 500mbps) will be more than adequate.
For most typical use cases latency is far more important than peak throughput - eg when browsing a website your browser will request a large number of small files (the page itself, scripts, css files, images etc) and may make lots of different connections to different sites to retrieve these files. Each file itself is quite small, so most of the time will be spent doing a DNS lookup, making the connection, handshaking SSL, sending the request etc. Actually receiving data is a very tiny fraction of this.
Also sites which use newer protocols (TLSv1.3, HTTP3 etc) will generally handshake faster and thus load much more quickly.
Latency also matters most for gaming and video/voice calling. Throughput does not matter over a certain (usually very low - eg 3mbps for zoom) threshold.
Video streaming will not benefit from higher bandwidth or better latency so long as you have enough to handle the stream. Netflix for instance recommends at least 15mbps per 4k stream, so long as you can sustain 15 * number of users + some spare you don't benefit from higher throughput.
Plus if you're using wireless rather than wired ethernet it's likely your wireless (signal strength, congestion in the vicinity, distance/obstacles from access point etc) will be the bottleneck - wireless connections are only going to be able to exceed gigabit speeds under pretty optimal circumstances and using the latest equipment.
Your connection will only be as fast as the slowest link in the chain, no advantage having a 1gbps connection if your wireless can only sustain 500mbps etc.
