Best mods for the vanilla game

I started playing The Sims 2 again a month ago and I'm loving it, but I want to add more excitement and fun with mods. What mods do you consider essential for a game? I've never used them before, so I'm open to any ideas, recommendations, or YouTube videos you might have. I was thinking of installing a trait mod and a Community Time mod.

Just so you know, I have The Sims 2 Ultimate Collection with all the content.
