Check out yokoffing's uBO filter lists. Specifically #2 "click2load" which does exactly what you're seeking. Making auto play content click to load.

Check out uBlock Origin's per site switches - subheading "No large media elements" [1]

Then they said "click to load" they meant "click [the toggle button in the uBlock Origin panel] to load," not "click [the media element] to load."

Not sure what I'm doing, but whatever I'm using with uBlock Origin lets me click the media element to load it.
