I have long wanted to play a "Shapeshifter" Rogue. Even split Rogue/Druid with a splash of Warlock, with no Str or Dex to speak of (outside of Wild Shape) and relying on cantrips and spells for ranged attacks when out of Wild Shape.

Whilst the obvious Druid Circle would be Moon (Wild Shape being the characters primary combat feature), I'd be more inclined to go for Land to add an extra Cantrip and some clutch spells to the list, or perhaps Shepard for Speech of the Woods and Spirit Totem (mostly).

Arcane Trickster is probably the best option for Rogue Archetype, to enhance utility (and more Cantrips!) but a mind toward Mastermind or perhaps Inquisitive might not be a bad shout.

Fathomless Warlock offers an interesting additional adaptability with Gift of the Sea and (if pushed to 6th lvl.) Oceanic Soul. Good utility options from Invocations, such as Beast Speech and Mask of Many Faces round out the character.

The character would focus on utility, scouting and survival more than combat, but would be very good at it.
