Shooting at 60fps, export in 24fps
I always shoot videos with slowest 50fps in my camera, Full HD. like you said, it provided slow motion &amp; this setting has clearer movement. Sometimes I change back to 25fps when I meet some conditions.

Export in 24fps can be used for website, for example published for vevo, youtube channels etc. Because fast buffering and light file size. It also for animation &amp; Music Video (MV). Full HD.

Export in 30fps is for NTSC Television Boardcasting &amp; it smooth for NTSC live, like TV shows in America &amp; Japan. If you published a video in 30fps alike TV shows.
Other countries used slow motion, able to published in 25fps for PAL TV. FHD, QHD. Mosty they're 4k now, their videos are very sharp.

Cinematic will be more optional and more setting &amp; editing, mostly people used as many as fps their camera have, until 4k/8k 120fps+lighting achieved proffessional result. Export in 25fps, 60fps, etc. It is optional.

You want to be videographer,editor for Music Video, web, etc? Export in 24fps. (Actually your camera fps setting &amp; export is good enough, just remember the quality of camera shoot, quality of resolution FHD or above)

Or Videographer,editor for live or non-live boardcasting TV shows? Export in 30fps. (The researched answer is for Television Boardcasting, 30fps)
