Good catch, Seth :-). Apparently this topic has been discussed in the past in bug #1822370 and https://lists.debian.org/debian-devel/2019/04/msg00010.html. Those discussions resulted in the decision to revert the IPQoS default values from openssh, which is something we're still doing. The default value for Debian/Ubuntu packages is "lowdelay", which, from what you said above, seems to be what's causing the problem for you.
This can be caused by how your router is handling QoS packets, for example. Either way, could you test this using a Debian testing container/VM and check if you can reproduce the issue there? If yes, then I would suggest opening a bug against the Debian openssh package, which is the best way to implement/discuss this decision IMHO. If you do so, please link the Debian bug here so that we can also keep track of its progress.
