USTRUCT(BlueprintType)
struct FTaggedInputAction
{
	GENERATED_BODY()

public:

	UPROPERTY(EditDefaultsOnly)
	const UInputAction* InputAction = nullptr;

	UPROPERTY(EditDefaultsOnly, Meta = (Categories = "InputTag"))
	FGameplayTag InputTag;
};

/**

UCLASS()
class MYPROJECT_API UInputConfig : public UDataAsset
{
	GENERATED_BODY()

public:
	// Returns the first Input Action associated with a given tag.
	const UInputAction* FindInputActionForTag(const FGameplayTag& InputTag) const;

public:
	// List of input actions used by the owner. These input actions are mapped to a gameplay tag and must be manually bound.
	UPROPERTY(EditDefaultsOnly, BlueprintReadOnly, Meta = (TitleProperty = "InputAction"))
	TArray<FTaggedInputAction> TaggedInputActions;
};

You definitely want to replace the TArray<FTaggedInputAction> TaggedInputAction by TMap<FGameplayTag, UInputAction*> TagMap and scrap the struct FTaggedInputAction as well as FindInputActionForTag. It just becomes TagMap[SomeTag].
