It all depends on the position. Even king safety. The more equal the position, the less you have to worry about king safety. Targets can be in the very beginning stages (starting with gambits), so material advantage doesn't matter so much if you can gain an early positional advantage.
True, it's all ultimately relative to the position, which is why I added the "generally speaking" in there.
What would you say are the elements of chess strategy and how would you (generally speaking) rank them by importance?
EG
1) king safety
2) material (advantage or imbalance)
3) piece activity
4) space
5) pawn structure
6) initiative
7) time
8) targets/weaknesses (pieces, pawns, or squares)
9) endgame prospects (who would do better should the position go over into an ending)
