I tend to agree, and it is worth noting that the Austral-NewZealand tradition tends to also reflect the same one the Anglo-American one follows
Though there are exceptions...
As for any of the cards, both individually and grouped, it is worth reflecting on not only what others have said and why (whether it be posts or books), but also consider both the images and the set of images.
With regards to the Court cards, there are, of course, sixteen. The number of signs in the zodiac is twelve. The number of planets varies according to whether one uses its astronomical classification, its traditional usage, and which are to be included in such considerations (for example, Pluto and Cheiron). Nonetheless, there certainly appears no clear-cut correlation, hence one of the reasons for its variation amongst authors: they are attempts at reconciling two systems which maybe just don't meld that easily.
As various systems have already been mentioned, I will not repeat them here. To be sure, one aspect they usually have in common is an elemental correlation: once one has determined a fourfold correlation with the elements, and how these also relate to the sequence of Page, Knight, Queen and King (and its variations), and also how these relate to Swords, Cups, Coins and Sticks (and its
variations), then some astrological sequences become feasible.
Personally, I do not normally
relate the courts with astrological considerations (though this may actually occur during a reading in a specific situation), and tend to prefer to view the Courts as representating psychological dispositions at play in the situation at hand. This is one of the very rare instances in which I make use of Jungian-influenced classifications, correlating the Courts to the MBTI... as this has been discussed elsewhere, and deviates from the thread and this already quite long post, I'll leave it here...
