Here's a doc showing all of the changed moves and what got changed from SWSH. Notably, several moves from dlc2 are different from what we have now, even though they are unavailable.
Flags didn't match up at all, so they were skipped. I'll look a little more, if I find any that do match up, I'll add it and mention it here.

Edit: Immediately found target data that lined up, adding them now (in all cases, the move was just changed to " AnyExceptSelf ").
I have finished going through all the flags and have added them to the list of changed moves (adding a few more). So to see what moves where changed, here's the link here: https://docs.google.com/spreadsheets/d/1D8fcCXIsy_oE_SNtHUYV9q00Ta1ngQ27TAUFLcwK5xg/edit?usp=sharing
I noticed that Double Hit is now a 0 damage status move that has the following effect:
"The user adopts a hard-hitting stance to increase the damage dealt by its moves by 50 percent."
