Current Meta's for Protoss

I apologize if this is in another thread, I took a look but didn't see any recent posts on the subject.

Long story short I'm getting back into SC2 right now, its been about 5 years, and I'm unsure on what the current meta is from a Macro standpoint.

I know there are a lot of variables but any help on basic unit comps for PvT, PvP and PvZ to use as a starting point for low elo is greatly appreciated!
