So far in BG3 Arcana, Religion, History and Investigation has come up I think.
These are very helpful tools, and Larian is using them a lot more than most DMs. I personally don't feel it's a dump stat, and unless I have a Wizard in the party I tend to put the crown on my character just to get 18 Int.
Honestly, I think Int is rolled just as much, if not more than Wisdom checks. But both are used very similarly to gain information.
And Nature. at least its stated as governed in character creation
