what settings do you use at wedding?
outdoor/indoor and what focal length?
The way you phrased that question it's really open to jokes. Are you asking what lenses and such?
Your average workhorse setup for a wedding on an FX body is going to be a 24-70 f2.8 lens, and a 70-200 f2.8 lens. You could get through an entire wedding shooting with those according to many wedding photographers (on DX using a 17-50 or 17-55 f2.8 lens and a 70-200 f2.8 lens).
Every photographer has different styles. I've seen some photographers explain that they carry with them two bodies to shoot with, and two bodies as backups. Some other ones use three bodies and utilize all of them throughout the wedding. For bigger more expensive gigs, you might need multiple photographers, expensive and quickly set up lighting, etc. Some weddings end up dishing out over ten grand for their photography, or even more.
Basically, fast zooms and good primes are best for weddings. As for bodies, FX and DX both have their strengths, but FX wins out for professionals and is better at higher ISO (and overall produces more pleasing images with the right glass). It'll come down to how many camera bodies you lug around (many photographers have one at hand and another on their side at the ready), what point of the wedding you're at, if you have any assistants, and what lighting you want... lots of stuff.
This is all based on what I know so far... watching YouTube videos and reading just out of curiosity.
