Well, I don't know anymore, but you need to look at the original files.
There are two bottles with the word Luna - one behind and one in front of the center of the target. The focus point is the word Fructal. You can see that Luna, whether in front or behind Fructal is equally in focus.
To me this says that the focus point is on the word Fructal.
The important thing to note is that the corners are definitely sharper than the center.
I have more than 30 Nikkors and this is the only lens where the center is softer than the corners.
Maybe I am expecting too much but to me the word Fructal - the center - is not just soft but plain wrong.
I can't see how at f8 the corners can be sharper than the center.
"Did you ever manage to get those christmas euphorbiae to bloom again".
I think they did but to be honest I didn't notice them there until you mentioned it. Maybe I should stop worrying about lenses and try to smell the flowers more.

You can't use the two unsharp items (the luna bottles) to conclude it's got to be sharp in between them, it's too subjective. Try to find the sharpest line. I can't tell if you are perpendicular to the window or not, probably not, but the focal plane looks a bit like this:
In the bottom left corner of the left window, the red (box?) with white dots seems relatively sharp,
in the middle then: the backhandle of the wooden utensil holder behind the fructal juice and the window frame next to it (what I called wood panel before) seems to be sharp.
On the right: somewhere near or in front of the nektar juice (the napkin holder looks a bit sharp as well).
So, that's how the plane of focus seems to go to me with the focus behind the fruktal.
If you were relatively perpendicular to the window, is there perhaps some decentering / left-right asymmetry ?
BTW,
was this AF? the fructal box seems to be small enough that the AF could have picked the wooden holder in the back as target.
