Help trying to understand Project Management predictive documents

Has anyone seen a website with free project templates? whats been confusing is that different individual templates i've seen online have different things in their document which makes it a bit tricky trying to learn what people use in the real world. I have already passed my PMP exam, I just think studying for the exam is completely different from studying for the real world so could do with this resource if you know of some please. just trying to be job ready once I start jobhunting
