Started playing recently myself. At the start, recommendations have no idea what victory strategy you are pursing, and don’t get that much better at it. They do seem somewhat OK at recommending things that will solve particular problems that city has (slow growth, lack of amenities, etc), though maybe there are better ways available to you. Or, sometimes they notice that your city geography would support a particular wonder or give bonuses to a particular zone. So, if they recommend something that seems weird, maybe check to see if you are missing some mechanical concept. (VI has a lot of obscure interlocking mechanics that can be hard to see, particularly at first.)
