Others haven't said so but maybe you should try Warbreaker as it's the "most" standalone book of the Cosmere saga. It's the "most" in the sense that there are still subtle references to other works but they are very minor and you can totally enjoy it without reading the rest of them first. In fact, once you read Warbreaker you can see some connections with it later on the Stormlight Archive
