10Gbps fiber is between 10 and 100x the entire bandwidth available to a typical small college with a few thousand students here in the US as of say 5 years ago.
These days bandwidth has gone up a lot, but it's still the case that it requires very much higher powered routers than what was state of the art 10 years ago (ie. an archer C7).
For your 200Mbps symmetric connection I recommend an inexpensive managed switch, a RPi4 with UE300 USB dongle, and a wifi access point (your existing C7 would be fine for wifi access point).
That will handle the required Wireguard and SQM with lots to spare. For proof see my thread on routing/shaping speed
For a home user, an SG108e from TP-link or the Zyxel GS1200-8 are good choices for managed switch.
