Well, Madhox here @ MTS did some amazing downloads that are add-ons for the game

Just download everything.
Peacemaker also did add-on's for the game so just go download everything of his as well!!

The difference is that some of his add-on's have different names, but they are based off of the original game. What I love about his stuff is that he updates frequently and his aesthetic is really pleasing.
You may have to run Madhox's stuff through S4S to update. Her stuff is gorgeous though, and I highly recommend having it.
I would search using maxis match add-on's for sims 4
I did find this thread on the forum

Maybe check Lana's cc finds as well, Sims4Studio, and Brazenlotus has some add-on's, but she also has a lot of separated original maxis items as well, which you can't get with the buy debug cheat in-game. These items are tiny in size, mostly, so they won't bloat your game.
