A couple weeks ago my download speeds were consistently about ~15-20mb/s and now they're always fluctuating to as low as ~800kb/s. I'm using NetworkManager with iwd backend.

wget -O /dev/null https://sabnzbd.org/tests/internetspeed/50MB.bin
to rule out the local storage.
Did you test the LTS kernel?
enp5s0 still works at full speed?
Otherwise, can you test the LAN performance w/ eg. iperf3 (that's gonna require two LAN hosts running it)

Not sure what happened but it's stable now even without changing anything, so I'll mark as resolved.

Between you and the internet is your ISP - and they all suck.
So if/when the issue re-emerges you want to test the LAN throughput to ensure it's a problem with your system or LAN config and not simply your ISP.
You can also test the system in a different context or at least make sure that other devices in your LAN have decent performance.
