That sounds about right for a consumer CPE router. I believe there is usually a hardware bottleneck between the SoC and the Ethernet complex that is significantly narrower than the Ethernet ports and switch fabric. Once the downstream gets saturated there is also no room for upstream traffic.
You could set it up for 100Mbit down, 25Mbit up using Cake, and see how that works. It'll be a major improvement over 8/1 DSL, even if it isn't using the full advertised capacity of the cable.
One device that should be able to keep up is a Raspberry Pi 4 (not the earlier versions) supplemented with a USB3-attached GigE dongle. Pete Heist has established that it can sustain 600Mbit through Cake without much CPU load or added latency. Above that level the characteristics do degrade a bit.
