Companion file size

I am looking into getting HG, and HG companion, and getting a tablet to use it on with LTE, since I could be using this up to an hour or two away from home and am concerned with losing the data between a location and home. I am wondering how big an “average” file you upload to the cloud would be for an “average” home inspection. If you could generalize how many pictures, videos, and voice memos you tend to use, that would also be helpful in decifering how the file size translates. I’m mostly curious to determine what kind of data package I may need.
