I picked up a Nova G3 chuck and have thus far really enjoyed using it with the jaws that it came with. I’m considering buying one or more new sets of jaws. I’m eyeballing a Cole jaw set (link below). I also want to pick up a bigger set of regular jaws (second link below). As with most things I like to set myself up for the widest variety of uses. Are there any other things that I should be considering? Any general advice would also be much appreciated. Thanks!

That is wide open. It really depends on what you want to turn. BTW I have 7 Novas with different jaws on each one.
The following is just my take.
Pin Jaws. One of my favorites. Drill a 1” hole about an inch deep, slap it over the jaws, expand, bring up the tailstock and turn away with almost zero chance of an orbit. Also holds small tenons down to about 3/8” which is handy for bottle stoppers and some other items.
70mm Jaws. Probably my go to. Over 50% more area to break away compared to the 50mm jaws using a tenon and allows a larger tenon.
100mm for big items.
My least/never used are the 35mm bowl and the mini-cole. The cole have never even been taken out of the wrapper. From my understanding the Cole are used to finish the bottom. If I had to remove/replace the 8 jaws screws and possibly move the 8 pin screws I am about 96% sure I can slap in a friction chuck, turn to a 1/8-1/4 nub and sand it off before I ever got the chuck changed to the Cole jaws. Some folks do love the Cole jaws.

So for what I do; the Pin Jaws. For a 12” or under lathe probably the 70mm jaws, for lathes up 16” I would go with the 100mm jaw instead of the 70mm.

I agree with LeeMills on the 35mm jaws. However, the Patriot chuck jaws by Sorby fit the Nova chucks and I am very happy with their 35mm jaws which can hold a tenon smaller than the 50mm jaws but larger than the tiny tenon needed for the Nova 35mm jaws.

To be clear, I was referring to the 35mm Bowl Jaws as being useless to me.
On the other hand the 35mm Spigot Jaws are great and I use them fairly often.
Nova Bowl Jaw series are measured from the exterior but the Spigot Jaws are measured from the interior.
The 35mm spigot jaws can hold down to 35mm or about 1-3/8 where the 35mm Bowl jaws hold down to about 3/8”. They make it easy don’t they? :)
