No, 'suit' usually has a person as the object, more like jmdm. passen (= gefallen) or zu jmdm. passen (= richtig sein).
'Concur with' often has a person as the subject, e.g., you concur with someone's opinion. It could work in your last sentence, but it wouldn't be my first choice in general with a thing (data) as the subject. 'Coincide with' or 'correspond to' might work in some contexts; the former is more random, more by chance, a lucky match, the latter is more neutrally descriptive.
'Match' is usually more 1:1 than 'fit,' but either one could be used for data. You can make the data fit a hypothesis, but you can't force them to match if they don't match. That is, fit is more like adapt to, explain the logical connection so that it makes sense, is plausible; but match is more like if you had an actual second set of data for direct comparison, perhaps the ideal hypothetical set as generated/predicted by a computer model vs. the empirically observed set as generated by experimental observation, lab tests, etc. But there's some overlap; there are probably contexts where either one would be okay.
Hard to say more specifically than that without a few sample sentences; maybe someone else will have other ideas.
