For quick and dirty batch processing I love Topaz Photo AI. Just shot an event for a dog rescue group. Grabbed all the .heif images, dumped them into TPAI and off it went.

Saved to a folder, quickly cropped/straightened and sent a link to the organizers. On the plus side if you utilize "Enhance Faces" algorithm you can get some overly smooth but great for social media images that non-photographers will love.
