In my experience, "moot point" is also used to indicate that something is debatable and open to discussion. It doesn't necessarily mean that it is no longer relevant. The relevance of a point can be mooted (verb), and therefore be moot (adj). https://www.collinsdictionary.com/dictionary/english/moot#moot__3 So, in this sense of "moot", it is a close synonym of "debatable" or "arguable"

It's defined as: an issue regarded as potentially debatable, but no longer practically applicable, For example: "Now that downtown has been rebuilt and business is booming, building more parking spaces has become a moot point." Synonyms: disputable, disputed, unsettled Remember, they are disputable but only in academic terms. It's usually irrelevant to the problem at hand.

It means it's unimportant. A moot point is an unimportant or irrelevant point. Point can mean anything depending on context. But to answer your question, the two words irrelevant and / or unimportant would be your answer.
