Networking researcher here. Your bottleneck wouldn't be the NIC, but memory bandwidth, CPU compute (for TCP), PCIe bandwidth, and Storage bandwidth, also the bandwidth of the server you're connecting to. You'll also need some sort of fiber SFP connection for your entire house, and those have firmware that usually makes them vendor locked. Most networking issues are also latency related, so increasing your throughput to 25Gbps wouldn't help.
So yeah, not a good time for home use.

I'm pretty sure that nic cards for those speeds would really need more hardware offloading and dma to stand a chance of those speeds. With those it should be possible. With the right hardware handling there shouldn't be a problem, ssds connected to pci manage a lot more. In real terms, right now who needs it aside from to post speed test results? I have gigabit symmetric and can upgrade to 2.5. But, I cannot imagine we'd need 2.5 let alone 10 or 25. And I'm a fairly heavy user.
