Does 10G nics for home servers actually do anything? I have a gigabit router and the motherboard on my server is 2.5G. Wouldn’t the 10G be throttled once it hits the 1G router and then only send out that speed to all other devices? Would I actually be getting better speeds than what I pay for also?

The point of a 10G NIC is to be 10x faster than a 1G NIC. Most 10G NIC’s only work at 1G and 10G, they do not do the new 2.5G or 5G, for that you need a newer 10G NIC that will use these lower speeds which in terms makes no sense because you can just get a 2.5G or 5G NIC instead. You confuse your internet connection with your local network. Your local network can run at 10G while your internet runs perfectly fine at 1G, the other way around the same. If you have a 10G internet connection you need a 10G local network to actually make use of that 10G internet connection. If you have a 1G internet connection, the only reason to have a 10G local network, is because you have lots of data that you regularly move around, and you think 125MB/s is too slow. Other than that, there is no need for 10G in any home network.
It’s mostly for internal stuff with a NAS. Uploading and downloading files off a NAS or streaming 4K content can all benefit from 10G
uhhhh…
to get 10G speeds on your network!
In 99% of cases, 10G makes no sense in home servers.
Because in 99% of cases “homes” typically have predominantly 1G networking and Wifi as the “Access network” with only a handful of users on it, usually not at the same time.
To upgrade this “1G” standard home network to anything faster will require the infrastructure be made available for higher speeds AND that the client devices are capable of taking advantage of it.
Concretely speaking, you will need to introduce a “switch” with higher speeds as well as upgrading the NIC in any currently 1G devices to the faster speed as well.
Practically and budget consciously, 2.5Gb is the present day sweet spot for consumer/pro-sumer “home” networking. It is relatively cheap, compared to 10G which “can” require a rewire if the CAT5e is substandard.
I have a single 10G link. It goes between two 1G + 2.5Gb switches. I used a simple “DAC” copper link between them.
I have 2 additional 10G ports, so I could link the two Proxmox servers which would take advantage of that speed during migrations and backups, but nothing else on the network is 10G capable or even close to needing to be 10G capable.
10G hardware typically costs a lot more to run. A 10G port might consume twice the power for the same data, even if it’s never hit more than 900mbit/s.
Use-cases which could justify a house-wide 10G upgrade might be, video streaming. I don’t mean playing a remote MP4 off the NAS via plex. I mean real time video streaming, such as lossless video conferencing, remote desktop with full 4K 60FPS playback capabilities. HDMI over Ethernet and so forth. Live uncompressed security camera footage etc. Remote gaming, ie. having a single beast of a gaming server with enough bandwidth to stream 2 clients at 60FPS. More bandwidth = less compression = less CPU = less packetisation delay = less latency = better gaming.
