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.
note this is still without cake, and neither core seems to be saturated yet.
I do have a Turris Omni that I plan to move this to, but I was expecting this
one to give me reasonable speeds on just a raw connection.
I will need a device with at least 3 ethernet ports (DSL, cablmodem, LAN)

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.
