Use your 24-105 for everything IMHO, bounce flash. Try not to have people in rows, it complicates lighting. Don't be afraid of higher ISO, 1600 is no problem at all on modern cameras, higher is often fine too.
Whatever you do; don't disregard the "use higher ISO" advice for indoors stuff. Maybe even 3200 or higher on 5Diii.
Also; bring a white paper for periodic WB shots, and shoot in RAW. A few WB shots can be a life saver in PP.
If only they made correctly balanced tie clips or something.
Also; if it's incandescent lighting, try to use a gel on your flash to minimize the mix of lighting colors. If it's florescent or a mix of daylight from a window, then gelling can be more complex.
Lens choice: 24-105 f4 will reduce DOF complications. Although, 70-200 f2.8 is a sweet event lens on FF! For moments without much motion, AF problems with thin DOF isn't such an issue and f2.8 reduces the need for flash / lighting expertise and opens the door for more natural looks. Not to mention reducing complications of mixed light color from the flash.
If you do have 2 cameras, be absolutely sure to sync the time.
For the rare times I do a friend's wedding, I like bringing an old camera with a cheap lens and handing it to a responsible looking kid - 10 years or younger. They get the best smiles. PP needs a lot of straightening but those little ones are really industrious. A little too industrious - prepare for 30 shots of the exact same thing LOL.
