Indoor agriculture has many advantages, but it also needs cheap land, and cheap energy. That usually means a balance between close to major urban centers, but far enough away to have a lot of room (including solar). Greenhouses, even tall ones, with multiple stories is the path to go. Solar and owning land means complete cost certainty for energy.
Advantages include low water, pesticide, fungicide, long growing season, high yields, and resilience to climate. It is global south and high north that need the resilience, and who have the most threatened agriculture states.
