Adjectives that describe something is well-recognized?

I am looking for an adjective (single word) to describe something that is well-recognized (that it is able to serve certain functions). It is more on the common knowledge side, not on the side of "just being popular". Some close adjective that I can think of is cherished, valued, etc., but they still sound slightly off.

Thank you.
