Is CRS312 the *only* MT device that has 10G ethernet port? IS there no single CCR (router) that allows to utilise 10G from SFP over ethernet, without having a separate (in this case) switch?

I'm am sure you understand the user was asking for basic ethernet not for SFP+ with a module type of ethernet.
Also, no reason for two discontinued models in the list.

Nope, the CRS312 isn’t the only MikroTik device with 10G Ethernet ports. Some CCRs, like the CCR2116 and CCR2216, have 10G SFP+ ports, but if you're looking for actual RJ45 10G Ethernet ports, that's rare on their routers. MikroTik seems to push their switches (like the CRS series) for that.
