Don't worry about it, you're limit to basic USB3 speeds, which is similar to the PCI interface on the Pi anyway (so PCIe2 single lane). You would gain more using the HAT so you can push it to PCIe3 single lane if using NVME and hang the SATA drives of the USB3 ports.
Looking at some sustained transfer speed, back in the old MX500 SATA days (which is about USB3 speeds on the Pi) it sustains at that speed. So I doubt any drop would be slower than USB3 with newer drives and would saturate that SATA HAT with more than one drive (or 2 drives if it can be pushed to PCIe3 setting.
See if anyone has made any graphs.
But I would look for power efficiency over outright speed. Keep it as low as possible hanging of the USB.
What do you expect to gain from a USB ethernet, 2.5GB speed?,.I'm assuming your network can do that.
But wait for other opinions too.
