What are you best practices for creating differentiated messaging while still keeping it simple/not too full of jargon so it best resonates with customers?

Always put your customer hat on! Put yourself in your customer/consumers position and use that lens to pressure test the 'realness' of the messaging. Does it make sense? Is it clear? Is the value proposition clear/unique/and resonates? It's amazing how often you can get caught in your own bubble and becuase you're close to your products/solutions/services..you do add jargon, you do describe things from an inside->out nature vs ensuring your customers are truly understanding your USP!
