The film's story and characters emphasize personal sacrifice for the greater good. Positive traits like bravery, thoughtfulness, and inner peace are demonstrated throughout by the heroes. A key element of the film's plot hinges on racial acceptance between two alien groups. The villains are sharply defined, and their behavior is cast in a purely negative light.
Though there are no curse words and very few moments of derogatory language, there's a bit of potty humor -- for example, a lead character stepping in the droppings of an intergalactic creature, or another creature passing gas.
The film takes place "a long time ago, in a galaxy far, far away," so there are no real-world product placements. But the Star Wars film franchise is perhaps one of the most heavily merchandised in the history of film, with action figures, kids clothing and accessories, and every other type of product available even today.
