What width should I choose: 400, 420, or 440mm?

A general guide: choose a bar width that matches or is slightly wider than your shoulder width at the AC joints. Most Indian male riders fit 420mm; smaller-framed or female riders often suit 400mm; taller or broader-shouldered riders may prefer 440mm.

Is this compatible with Shimano GRX Di2 (12-speed)?

Check your specific GRX Di2 junction box and cable compatibility. The EW-RS910 port is a standard Di2 junction point — confirm with your mechanic that the specific generation of Di2 you're running uses EW-RS910.
