The method I used to get to level 99 in KH3 with Sora took me less than 2 hours to get from level 40 to 99. Unfortunately, you have to have beaten the game (or gotten very close to doing so) to have access to the area I farmed XP. I was getting 40,000+ XP every minute to a minute and a half. Also easily farmed well over 5,000 kills for the respective trophy.
