While this one agrees in principle that the spell list should be tweaked and expanded, this one would prefer if the lion’s share of those spells directly match to literary examples.
Hour of the Dragon mentioned quite a bit of the nasty things Sorcery can do.
Now, some of what was there could have been dependent upon the Heart of Ahriman or, it’s scope may have been impacted by the presence of that fell artifact.

What we do seem to be short on is mind control and curses/afflictions, especially those which spread diseases.

There is a diseased condition in game. That is such an obvious choice for the type of nastiness Sorcery could do.

Furthermore, Harvest Resources should have a lesser version, one that just destroys the resources, blighting the land.

Continuing with this theme, many things in this game have a decay timer, that is something sorcery would be perfect for clucking around with, either rotting good meat, or preserving the freshly harvested heart of a hero…

To say nothing of more weather manipulation, which would have been more useful when this was a survival game.

But getting back on track, more spells would be nice, but it is unlikely that any D&D spell list will receive a warm reception from those who control such things.
