I've personally never been afraid of using mods or them breaking my game, so I've used them ever since the first game. I never had any problems with mods breaking the game either. I think it's more a case of going to trustworthy websites, doing your research and making sure different mods don't conflict with each other so everything works as it should. The Sims 4 is a pain to download a lot of mods for though since you need to redownload almost all of them after every single patch. I do it anyway because I don't want to play the game without.
Mods aren't as scary as you might think and Slice of Life is very safe. I've been enjoying it myself for a while now. ?
