Actually, many consumer gigabit Ethernet switches lack 10Mbps support these days. They are 100/1000baseT only.
Business and enterprise switches though I've found (including Cisco ones, which you can find dirt cheap used) still are 10/100/1000Mbps. Even newer business and enterprise class switches retain support.
I have a HP Aruba 3810M, 48 port PoE, 40 of them are 1G and 8 are "SmartRate" 10G. It's consider "obsolete" and nearing EoL. It does support 10M on the 1G ports but 100M is the lowest you can set it from the browser. You have to get into the cli to force 10M. It does not support 10M on the 10G ports, and while the spec sheet doesn't show it the option to lock to to 100M is in both places so I assume it actually does. I might have to go play around with this later with some 10/100M cameras I have.
Of course, once you step into 10Gbps Ethernet, you have to be careful because many only are 10Gbps only, while some do support 1/10Gbps. 2.5Gbps support is iffy unless it's specified which is annoying since many things have 2.5Gbps ports.
I've only seen that with SFP+ which it also has 4 of. Spec sheet for the uplink module says 100M/1G/10G. As they specifically mention 2.5 and 5G on the SmartRate ports I suspect the module can't do those. Which matches up with the other things I've run across. But I'm not going to buy a 2.5/5G transceiver to test that lol
