I have effectively unlimited 5G data on my phone, and a 1.5Gbps connection at home, and yet, yes you should absolutely design for iffy internet. I commute in tunnels where signal can drop out. I walk down busy city streets where I technically have 5G signal but often degrade to low bandwidth 4G because of capacity issues. I live in Australia so I'm 200ms from us-east-1 regardless of how much bandwidth I have. It's amazing how, on infrastructure that's pretty much as good as you can get, I still experience UX issues with apps and sites that are only designed for the absolutely perfect case of US-based hard-wired connections.
