What is the advantage of using the optical zoom versus cropping in post production? I find myself always cropping because I can take my time and see what I'm getting more clearly. But I'm a new user and would like to use this cool camera to its full advantage. Thanks.

a few advantages i can think of immediately:
perspective: the zoomed picture will have less distortion than the wide setting.
depth of field: you get a shallower depth of field while zoomed.
image size: when you crop, you get a smaller image, by zooming you get the full size.
a disadvantage: 1.8 on the wide end is faster than 4.9 on the tele end, so if you really need a faster shutter speed on lower light situations it might be more interesting to shoot it wide and then crop.

that's a question usually asked about a digital zoom.

Rx100 and rx1 have two digital zoom modes

- normal
- crystal (if I remember name correctly)
Crystal does the digital crop to the fov that u digital zoom to but also tries to fill in the missing pixels (could be using an algo similar to genuine fractals that was popular a long time ago..) it can slightly better or worse then normal digital zoom, depends on the content of picture.
Back to the op original question. 20 mp sensor has a lot of info that u can use to crop an image no matter where u are in the zoom lens range. Depending on how big u print will depend on how much u can crop an image.
I normally do not crop more than 2x the fov of any sensor 16mp. The rx100 will give me slightly more.
I tend to use the zoom but I will crop even the zoom for three situations
- wide end crop to get the 1.8 aperture due to low light or staying in certain iso range
- the long end because I need a longer lens
- a grab shot, use whatever the zoom is set for and just get the shot (sudden candid opportunity)

If you use optical zoom, you can zoom in further by cropping.
If you use optical zoom, you can print bigger because you've got more pixels.
Try to use optical zoom as much as possible and crop to finetune. I try to get it right straight out of camera, but I don't mind a little cropping to improve framing.
