Beginner Surfing Etiquette?

I didn't really know how to word the title, so I decided to just call this etiquette because I suppose it could be. If a beginner is riding a foamie longboard and decided to paddle past the white water and ride some of the bigger waves (chest to head high), would that be something that they shouldn't do? What if a beginner is riding a performance shortboard? Reason I'm asking is because I'm planning on taking a mini surfing trip in February, and I don't want to be stuck in the white water the whole time. I'll rent out a long foamie and probably try a few shortboards for the heck of it. I don't wanna get smacked in the face by someone's board because they are agitated. Maybe it's best if I go to a beach that's not busy? Would good surfers care if I went out to the lineup with a foamie/shortboard as a beginner as long as I wasn't in the way and made sure to use good etiquette?
