Dual-band wireless routers are only useful for speeding up the data throughput of locally connected devices, and then only up to the maximum throughput of the two devices connected to each other, with the limiting factor being the slower device.

You may be right, but that is not the understanding I got from this article: How To Buy a Wireless Router: The Short Version - Speed, Choose Type, Products

I would still spend a little more and go with the dual-band, dual radio model.

Your router is a switch. Those are point-to-point and don’t go through a bottleneck of the “slowest” device.
