In a job cover letter I've written "Only last month I heard great things about the clinic while attending a conference." My first question: are 'only last month' and 'just last month' interchangeable? Is one better than the other? Second, while trying to find an answer via google I saw instances akin to "Only last month, I heard great things..." Should there be a comma after 'month' or no?

    Only last month might introduce a contrast: "Only last month, I heard the food was delicious but..." Just last month might emphasize how recent it occurred: "Just last month, I heard the food was delicious, so I'd have confidence it still is." Commented Mar 27, 2020 at 21:41

There is not associated with the word "only" in this usage the usual idea of singleness but on the contrary the implicit announcement that there are or that there has to be more instances to come or more instances in existence. This might come after a contrary statement or context so as to invalidate it, but not necessarily, it might be uttered or written as means of emphasizing a non-contradictory statement or context. The sentence in the question appears to be about emphasis. It does not seem to be a recorded usage in the SOED I own. However, I am fairly sure that this is the meaning that should be given to this phrase, whereas in the case of "just last year" I am much less certain of it as a synonym; this is due, I think, to the fact that the additional interpretation of "just" as "recently", which is possible, makes it ambiguous. However many example from the books might confirm that this is true and I provided some so as to give the interested reader a means of appreciating him/herself what comes out of all that; the collected examples, if I interpret them correctly, would show that there is no real difference between the two forms: in this context they appear to be synonymous. In conclusion, I'll say that the form with "only" is sounder.

I'd use a comma, but usage concerning that point seems to be divided, as show the examples from the books below.

  • "Only last month, I heard great things about the clinic while attending a conference."

(Note    I think that this following syntax, that should not include a comma in my opinion, is not interpretable as a case of invalidation or emphasis.

  • Only last month did I hear great things about the clinic while attending a conference.)

  • LPH, your descriptive answer was a little hard to follow but the examples you provided were great and answered my questions. Thank you for taking the time & effort to look those up :) My conclusion from the examples is that 'only last month' and 'just last month' are interchangeable; it's just a matter of preference. Secondly, one generally does NOT put a comma after either phrase. Most of the examples above that contain commas do so because of what follows (e.g. 'for instance' and 'up at the rodeo in Calgary'), and not because of the 'just/only last month' clause.
