Now, despite the best intentions of you true experts, I am still confused. Some of you are saying I should never use a camera mounted mic like a shure or Rode. I understand that for filming from 10-20 feet away, it is not going to be perfect, but I have to make the best of it. For my niece's wedding, not only can't I afford them but I simply cannot show up with boom microphones, lav mics, recorders etc.
My only choices are to use the built-in mic on my 80D or the built-in mic on the Sony 4k camcorder I am expecting from Adorama today, OR use an external mic attached to the camera. I thought my original question specified that I was considering various Rode mics for on-camera use; if not, it should have. So, any last thoughts?

Yeah, good luck with that! If there is an audio rental company near you, you may be able to call and reserve a wireless setup for the day. AV companies that serve the hotel meeting market or the local theatre market are likely to have what you need.
The inverse/square law (1/d^2) can be your friend or your enemy. The boundary of that relationship is around three feet away from a source. You can't escape the laws of physics, no matter what you do. At ten feet, you will have 1% of the sound pressure level you had at one foot. At 14.14 feet, half a percent. At 20 feet, one quarter of one percent. But the signal-to-noise ratio goes in the OPPOSITE direction. That's because you're turning up the gain (or the AGC circuit in your camera does that) to compensate for the reduced sound intensity.
That said, If you "just gotta," get the most expensive Rode you can afford, and get as close as you possibly can. Outdoors, use a dead cat windscreen if possible, or a foam windscreen.
I can't stand the sound of any on camera mic... It's truly meant for synchronizing the waveform visually, to a track from an external recorder, during post-production (or, more cynically, as a gimmick to entice amateurs to use a dSLR for video).
Do a test run under similar conditions as you will encounter. Be mindful of what's behind the mic. The tighter the supercardioid (shotgun) pattern, the more the mic picks up FROM THE REAR. That's why, outdoors, you hope to be far away from airports, so you can put the mic on a boom and aim it down. Indoors, if you're using a boom, stay away from HVAC vents.
Outdoor weddings are a pain in the posterior to record. Wind, birds, vehicles, planes, boats (I've done a couple of wedding videos lakeside), and other noises (construction!) will obscure timid brides and fainting grooms every time! Couples are nervous enough as it is. They almost NEVER project loudly enough for people on the front row to hear, let alone people on the back row. It's bad enough in a church or similar hall, where you have tattering toddlers and crying babies and coughing family members to contend with.
