1. many/a lot of different sth
variety of reasons/ways to do sth
A 'wide variety' of items is an expression that has a positive connotation with choices of objects or the selection of things on offer. If somewhere has a wide variety, it means you have a lot of choices when it comes to making a decision: "I recommend this car dealer. They always have a wide variety of second-hand cars to choose from." You might hear this used in reviews of businesses or restaurants to talk about the 'wide variety of food or products on offer.' In advertising, it can be used to boast about the number of items for sale. Similar to a 'vast selection' or a 'wide array'.
