So we already know that the Nook Mile items are divided into groups and you get a certain selection of groups available on your island. To me, the next logical step is seeing if these groups also determine the items available in Nook's Cranny or if there's at least some sort of pattern, but so far I haven't been able to find any research done on this online or whether it's been proven/disproven (and if it's true, what are the groups?), so I thought I'd set up a survey! So far, from what I can tell based on a very small sample size, yellow airports give the blue imperial series, for example.
If you want to do the survey, just fill out the Nook Mile item groups you have based on the image posted below (in the spoiler since the image is pretty big; I just added numbers to the groups to make it easier to identify them; for example, mine are Yellow-5355) and the variations of the furniture items/sets given (there are a lot listed so that you can just fill in the ones you know if you're not sure about all of them, but I believe the catalogue on the Nintendo Switch Online app lists your native variation first, I haven't checked the in-game one though).
On a somewhat unrelated (but also sort of related) note, I have another theory on the groups in that some of them are partially dependent on each other, so some combinations of groups would be impossible.

I'm guessing that each island has a certain numbered seed and then a modulo operation is used with that seed on the number of variants there are of an item. For example, all islands with red airports might have a seed equal to 4k+1 for some integer k, while green airports could be in the form 4k+2.
If that's true, then if your seed is a multiple of 4, then it must be equal to either 8k or 8k+4, so in the public bench/phone box group, you only have two possibilities to choose from. Similarly, if your seed is a multiple of 4, then it's equal to either 6k, 6k+2, or 6k+4 for some integer k, so for each airport colour there are only three potential lighthouse colours instead of six, because three of them correspond to 6k+1, 6k+3, or 6k+5, which can never be a multiple of four.
I looked through the data given on this thread and came up with the following:
- Yellow airports get public benches in white or black/white (along with the phone box in the same group)
- Green airports get public benches in green or green/orange
- Blue airports get public benches in red or blue/pink
- Red airports get public benches in blue or blue/yellow
- Airports that are yellow or green can get lighthouses in red, yellow, or blue (along with the other items in the same group)
- Airports that are red or blue can get lighthouses in white, grey, or black
If that's true and the furniture in Nook's Cranny is based off the same groups, we could find out or at least narrow down quite a bit of the possibilities for native furniture variations just by looking at the airport colour, and we could find out if, say, the rattan series colour determines the antique series colour.
