Is there a cheap as in < $1000 router with 10GbE (for fiber or copper) ports?
You pay the SFP module tax on every port for that model, and also have a loud fan. You also probably can't put a copper SFP module in every cage without overheating.

That will let you receive 10Gbps fiber, and maybe route 3Gbps or so. No fans. No SFP module tax. And PoE on every port.
Mikrotik is definitely missing a product that has maybe 1 SFP28 port, 1 SFP+ port, 4 10GBps ports and 5 2.5Gbps ports. That would let you take in 25Gbps fiber, have a 10Gbps fiber run to a switch someplace, and run 10Gbps ethernet as needed.
Otherwise, you can get a powerful router with 2 SFP+ ports and link an SFP+ switch for the rest.
