Different adventures for different level ranges:
Lower levels: Dragon of Icespire Peak
Mid levels: PotA. The haunted keeps are great is written, but I would probably break up the elemental dungeons into four separate dungeons plus the fane of the eye and elemental nodes as the final dungeon.
High levels: the giant lairs from SKT
