What AWS service is appropriate for storing a single key-value pair data that is updated daily? The stored data will be retrieved by other several services throughout the day (~ 100 times total per day).
My current solution is to create and upload a JSON to an S3 bucket. All other services download the JSON and get the data. When it’s time to update the data, I create a new JSON and upload it to replace the previously uploaded JSON. This works pretty well but I’m wondering if there is a more appropriate way.

There’s many:
^ those are some of the most common. Without knowing more I’d suggest you consider Dynamo or Param Store. Both are simple and inexpensive–although S3 is fine, too.
The only reason to not use S3 is governance of the key expires etc., automatically from AWS side – like using a secret manager – therefore, giving it to third parties will be much harder.
Your solution seems very good, especially since S3 IS the object store database – json is an object.
The system you described is such a low usage that you shouldn’t spend time thinking if there is any better way 🙂
Just make sure you are aware that amazon S3 provides read-after-write consistency for PUTS of new objects in your S3 bucket in all regions with one caveat. The caveat is that if you make a HEAD or GET request to the key name (to find if the object exists) before creating the object, Amazon S3 provides eventual consistency for read-after-write
and to refer to your comment:
S3 way is not hacky at all – intended use of S3 is to store some objects in the key-value database 🙂
