I recently moved and got internet with Spectrum. A 200/10 service yet my upload speeds were rarely above 5mbit. This was a business account with some web and dev servers behind it. I didn't even try to call customer service...
With a little more testing using UDP, I could see I was getting very spotty packetloss (<0.5%). I'd never tried changing the TCP algo before but I knew random packetloss is normally interpreted as congestion and hence causes a speed backoff.
I tried all of the ones available at the time but the one that stood out not only in performance but also simplicity was TCP-Illinois[0]. The stats provided by `ss -i` also seemed the most accurate with TCP-Illinois. I force enable it on every machine I come across now.

I highly recommend BBR congestion control if your router supports it.
TCP congestion control is end-to-end. Routers don't need any support for it.

I don't think you know what Bufferbloat is.
