This is really just a recommendation, but my group highly enjoys incorporating the broad diversity of Satire's Extended Gloomhaven Battle Goals into our standard Gloomhaven game. The battle goals are balanced and well-considered, and add variety in a campaign where players otherwise are likely to see the same handful of Battle Goals over and over. Installation is easy: Just save the new deck as an object and replace your existing Battle Goal deck with it.
