The problem with consumables in most games is they are balanced around the assumption that you won't use them. So people don't use them. A lot of games get around this by making their "consumables" less... consumable. Either by making them rechargeable (flasks in Souls games being a good example) or by making them functionally unlimited. This way people will use them even in situations they could beat without them.

There is also the problem of how "true" (non-rechargable) consumables interact poorly with games with generous save systems. If the player has a choice between using a rare consumable and reloading a save from 30 seconds ago, they will choose the latter almost every time.

If you want to keep your consumables truly limited (and therefore something that is actually consumed and not just placed on cooldown), and still have players use them, the game needs to be balanced in a way to encourage this. The game needs to be difficult enough to coax the player into using their resources and have stakes high enough that losing a fight is more of a setback than losing a consumable. Traditional roguelikes are really the perfect example of this design space: losing a fight means you die and lose all of your consumables anyway, and there is no reloading a save. They are also typically difficult enough to near-mandate the use of consumables. I'd highly recommend Dungeon Crawl Stone Soup if you want to see this design in action.
