Not sure that I can do that since I have custom stuff in-game like housing cc, and if I were to remove it, the house would be different. I'm just going to continue looking at my files with MCD and see what I can delete.
EDIT: still getting major lagging/freezing. I went into game under my current household, and I froze about 3-4 times in 20 minutes. Then I went into CAS and froze about 3 times in 20 minutes. CAS seems to be less lagging freezing than my current household, but its getting to the point where I just want to quit sims all together even though that's my fav game. I have tried literally everything, Changing settings, removing cc, 50 50 method, checking for corrupted files, updating game, repairing game. NO THING works.
