Is it logic to make point and click game in unity 3d ?

In 2d it's logic but in 3d ? Do i want the user to use the keys wsad ? Or the mouse with point and click ?
The game i want to do is adventure game where you click with the mouse on items to take. Like a quest.
But the moving part i'm not sure how it should be.

I also didn't find any tutorials how to make the point and click with the mouse for moving and for the items(inventory).

In my opinion the user should not pressing w for example none stop to move to some location around the scene. Since it's adventure/quest i think point and click is more logical.

But how do i start/learn the point and click movements and items ? Should i make A* pathfinding in 3d ?
