I found two new videos for Confirmation preparation that others might find helpful. They aren't Catholic, but they are well done.
This one I'm showing: https://www.youtube.com/watch?v=0HMryr1ZlxQ
I like this one because it addresses both belief in our 3 in 1 God, and begins a conversation about how we moved from "The Lord your God is One" to understanding the trinity. I do wish it used the words 'belief' or 'understand' a little more, and 'grammar' a little less, but I tried it for online prep and the group seemed responsive.
This one I wouldn't show (it's too fast and some of the language doesn't match what I would want to use and/or has a pretty protestant bend), but I will absolutely be using the balloon filled with air no matter how inflated it is to discuss being filled with the Holy Spirit. https://www.youtube.com/watch?v=B0wWA-dUyDM
