Check out Hume AI's website for a number of maps of various types of nonverbals that may be useful to you in therapy activities, particularly with teens, young adults or adults. I say that because some of the content on the website-- particularly the expressive language map-- is more mature. 

I'd suggest starting with the Facial Expression "galaxy" as I labeled it with students. Click within a cluster and explore nearby facial expression to discuss, for example, what makes surprised look surprised, in terms of what the face is doing.

We used this as a preparatory set with students before checking out videos with some kind of prevailing emotion. Anna Vagin has a great list on her site (and you'll really benefit from her email newsletters) and you can also check out resources such as this one from A Fresh Breath on TpT.

Scroll down on the main site and you'll see other datasets such as Emotional Speech, "Recordings of sentences being spoken in dozens of emotional intonations around the world"
