However, if you decide to broadcast one network with both bands, the connecting device will decide what band to use.

I'd recommend determining what standard a, b, g, n, or ac all current devices use and restrict access to the 5 MHz radio to n and ac devices exclusively.

Wifi works at the speed of the slowest connected device.

It's unlikely things like sprinkler controls and detectors use faster standards since they are not transmitting much data. No justification for the cost.

Also most residential cable was set up on 2.4 radios. While dual band modems are becoming more common 5 MHz is still less congested and the channel spreads are larger meaning less likely to get interference / congestion from neighbors.
