Well, Bach has many exciting rhythm patterns in his music. The accents certainly don't have to be on the first beat, but you will normally still feel the first beat as the most heavy part of the bar. What I mean is that the stress on the first beat is often felt even it is not played as the loudest note.
Often the stress on syncopated notes works because you kind of feel the normal stress on the beats and then play the syncopation against that so to speak.
Anyway in this piece the highest note, the f, will stand out because it is the highest note. You don't need to accentuate it. You could say that the accentuation is build into the music. The way it is written creates excitement and makes the ending of the piece really great.
By the way, the piece is written for harpsichord where you can not play an accent on the note, but as I said it stands out anyway because of the way it is written. When you play it on a modern piano the note will also stand out for the same reason.
Since it is possible to play an accent and/or make a crescendo and a diminuende on a modern piano that might very well be done. But you don't need to do that in order to feel the f somewhat accentuated as I indicated above.
