As I understand it the new AWD Ridgeline is largely the same as the old AWD Ridgeline, as in they are on-demand AWD systems. The only difference is I don't think the new one has the manual push button to lock in 4WD, it's completely automatic (with manual modes for different terrain types).My answer is, it does have less if you don't have AWD. In the 2007, yes the 4WD is push button for slow situations but even without it, the tow capacity is 5,000 pounds.
So a 2017 AWD Ridgeline should be the same as your G1 in most apects, plus whatever improvements they've made to the engine, transmission, and AWD system.
The only difference is that now they are offering a lesser FWD model for those who don't need the G1's capabilities and want to save money and a tiny bit of gas mileage.
It sounds like the easy answer for you is to just get an AWD version since you want the same thing as your previous truck. That doesn't help with the other weird feature options that are exclusive to the top trim levels, which is even more frustrating given that many of those features are standard on most/all of the trims in Canada.
