Seems a pretty straightforward decision to me: select the bar style you prefer (some form of either drop bars or flat bars) and buy accordingly.
Any of the bikes you mention will serve you perfectly well for the uses you describe. The only qualification I'd make to that statement would be to be certain the Giant Fastroad has the tire clearance you want, e.g. for riding gravel roads. I know that the Anyroad and the Sirrus do, as will any CX or 'gravel' bike you look at.
