There are some 5e specific utility scripts (I haven't used them though, just seen them posted). There are bunches of API scripts that are applicable to 5e. Nothing you can't live without, but things that make life better (turn tracking with player advance, ammo tracking, some powerful token state manipulation, automated lighting settings for players, auto numbering of monsters, auto hit point rolling of monsters, etc. ). Also, even with just one campaign you're running, the Transmogrifier can be great for shuffling data between campaigns (I like to have a monster campaign to store configured monsters in).
