Is this possible? And if so, how? 
        shopkeepers
            var/list/wares
            var/list/waresshow
            verb/Buy()
                
            Pubkeeper
                icon_state = "pub"
                wares = list(/obj/possesions/Beer)
                waresshow = list("Beer - 10G")

verb/Buy() hasn't been finished.
How to make the user choose Beer - 10G in list waresshow and then the program gives them /obj/possesions/Beer from list wares?

To do what you want would be like the following.
mob/shopkeepers/verb/Buy()
    var/selection=input("Buy what?")in waresshow
    var/item_type=wares[waresshow.Find(selection)]
    var/obj/O=new item_type(usr)
    usr<<"Got a [O.name]."

However, there is a better way to do this with associative lists.
mob/shopkeepers
    var/wares=list("Beer - 10G"=/obj/possessions/Beer)
    verb/Buy()
        var/selection=input("Buy what?")in wares
        selection=wares[selection]
        var/obj/O=new selection(usr)
        usr<<"Got a [O.name]."

Look up list associations in the help file.

Far better still is to allow the player to cancel their selection. (Although it's also a good idea to charge some money for the item, too.)
mob/shopkeepers
    var/wares=list("Beer - 10G"=/obj/possessions/Beer)
    verb/Buy()
        var/selection=input("Buy what?") as null|anything in wares
        if(!selection) return
        selection=wares[selection]
        var/obj/O=new selection(usr)
        usr<<"Got a [O.name]."
