What are the standard snap tools.

snapping is still clear to me. Which tools can work well together to create a drawing?
Is there a good example somewhere?

The most important snaps are Endpoints, Center (circle), Middle, Intersection. You can have them on all the time simultaneously. For most cases it is also advisable to have Free Snap on all the time.
