Good points on handlebar widths. The Jones bars have guide marks to be cut down to 660mm (carbon bars can be safely cut down), which is the width I use on my mixed surface bikes. For reference, I like 44cm hood widths on my road bike and 46cm on my gravel bike bars (which flare out wider in the drops).
As you have a bike that has the Jones bars, you've probably seen that with the 45deg sweep as you move your hands forward from the most rearward position the effective width narrows quickly. I frequently cruise with my hands near the intersection of the angled grips and the crossbar (it's kind of the hoods position on the Jones bar), where the width is around 44-46cm.
