Another option (if available) is to find couples that don’t have a huge budget set aside for a photographer and offer to to it for free as a way to get started. That way, you may not be under the same pressure as a full professional (€€€) shoot.
I’m hoping to do a shoot in Italy next year for some family members on my wife’s side. A few years back I tagged along side the photographer of my brothers wedding (also in Italy funnily enough) and got some nice shots after the main photographer set up the shot first of course :) He didn’t seem to mind either but I made sure to stay out of his way.
