I'd suggest adding Wi-Fi to the test matrix, with 802.11 MAC behavior as an
independent variable. Aggregation, retries, and EDCA queuing interact with
transport CC and AQM in ways wired tests won't expose.

Over-the-air testing (e.g. the meeting APs) is useful but hard to repeat.
For controlled runs, here's a writeup on driving 802.11 MAC conditions with
a conducted rig: https://www.umbernetworks.com/umber-devel-test-rig.html
