A Raspberry Pi 4 can route at gigabit speeds, even with a USB3 nic.[1]
There is also a router board for a CM4 module that adds a second nic through PCIe.[2] The nics still aren't super nice but they are more than good enough for a home router.
The problem is that you can't actually buy a Raspberry Pi right now due to supply chain issues, and that may not change for a while.
