Benefits of Adding Movement to a Pond?

[robert.mich]

I've found that water movement can have a noticeable impact on the overall look of a pond. Many larger properties use commercial fountains because they provide an attractive display while helping improve water circulation. While researching different approaches, I came across https://www.protopond.com/collections/pond-fountains and noticed several fountain styles designed for larger ponds. What factors do you think are most important when selecting a fountain for a commercial or community pond?
