The biggest up side to 2.5 gig and 5 gig is that they can do their speeds on existing cat 5e and cat 6 cables at their full 100 meters. And I think 2.5 gig poe is dirt cheap. Outside of reusing existing cables WiFi 6 and 6e APs are their only real use since they can peak just over 1 gbit speeds.
I will have to see that. I would be concerned about pushing cat5e that fast. I am not sure about cat6, but again that speed is not fast enough to buy new cards for the computers and if we were buying cards I guess the 10G fiber cards are likely cost competitive now that servers are dumping them as obsolete.
In terms of value old 10 gig is much better than new 5 gig and even 2.5. It’s just most 10 gig stuff has crazy loud fans and use a ton of power.
Noise doesn't matter in a data center which is where the switches live. The power use might be more than a 1gbit, but they're in line with any dual power enterprise switch really.
