I still love Adobe Spark. It’s pretty much idiot-proof. My first two videos were created using Adobe Premier Elements and Audacity. They came out ok, but were not as simple as Adobe Spark.
The two most difficult tasks are photo selection and narration. The experts say that 6 minutes is maximum length for videos like this. In my experience, the story dictates length. So far my max is less than 5 minutes. I tend to select the photos first, but sometimes writing the narrative dictates which photos to use for a story. In the end, it’s just fun to do.
