I've got fibre to my house. I could pay more for 1Gbps, but I'm currently on 500Mbps and it's good enough. Unless I worked in video editing or did AI training at home or something I don't think I'll upgrade. There's just not that many benefits to being faster.
I'd say even 100Mbps would be good enough for most uses. It's nice to be faster, but I'm not certain it improves my life very much.
