To me Space Opera is more about the plot (large scale, the main characters being important movers in the setting) while the Science Fiction vs Science Fantasy debate is more about the setting. That is, I think it's possible to have Space Opera Science Fiction (imagine if you removed the protomolecule and its tech from the Expanse and just had the Earth/Mars/Belts political story) or Space Opera Science Fantasy (Star Wars of course is the most prominent example).
