Is more than 1Gbps needed for that? That seems insane, but I'm old and watch stuff in full HD so what do I know.
Low latency means low compression. Low compression means high bandwidth.
1080p60 NDI will be 200mbps. If you are doing 2160p60, that's 800mbps (which is about the limit I would run 1gbe at). Doesn't leave much overhead for anything else, and a burst of other traffic might cause packet drops or packet rejection due to exceeding the TTL.
2.5gbps would be enough.
But I see 2.5gbps and 5gbps as "stop-gaps". Data centers standardised on 10/40gbps for a while (before 25/100 and 100/400) - it's still really common tbh - so the 10gbps tech is cheap.
I don't see the point in investing in 2.5/5gbps
