Be careful, though. If your agent gets a whiff of this, they're just going to steal your script and make the film without you.

Stupid question, but are you formatting the card in the camera before you start shooting? Generally speaking, that will sort out all sorts of issues.

I couldn't figure out the motivation for the time lapse stuff. At about :40, the shot where the cook is bouncing between all the pots, I loved the effect, but everywhere else it seemed just distracting. If the overhead shot let you see 30 minutes worth of potato's getting cut and piled up, for instance, it would help communicate the scale of the prep work, but now it just looks arbitrarily sped up.
Same thing at :54. Just one bowl of food sped up seems less interesting than half a dozen bowls filling in quick succession.

As far as audio, there's not a lot you can do to bring down the people talking around your interview subject, but in the future, a closer mic would help. Also, I had to put on headphones to figure it out, but at about :15, his voice sort of pans from left to right, then back left, then at :30 it snaps back to the middle at a cut. It's generally a good idea to shoot interviews on a single mic rather than in stereo, but I really don't know what's going on there.

There are a lot of cool shots in there; I think the arbitrary sped up stuff just detracts from what would otherwise be strong visuals.

Honestly, I edit most days off a spinning hard drive (1-2TB Western Digital, USB 3.0).* Pull all the files from the SD card and Audio straight to the portable drive and don't worry about downloading them every time you edit. Obviously, make a backup of everything on another drive somewhere else. Do a 'Save As' to make a new project file every time you start up, and just back that .prpoj file to dropbox.

*This works well for c100 footage; your mileage might vary if you're doing a lot of 4k/RAW video, but it'll be more convenient than what you're doing, and only cost about $45

wireless signal+no headphone monitor always makes me cringe

"guess we'll see how it sounded after we shot all day"

There was a 'how to shoot a protest' article a week or so ago that made that suggestion, but most lav mics are omnidirectional, so you're going to get tons of unwanted sound along with the person you're trying to actually hear. if you were to gaff tape a videomic (pro/go/whatever) to the transmitter, you might get more of what you're trying to hear.
