>>1802693if it's a carbon fork you need a compression plug aka a fork expander instead of the star nut, the star nut is too rough for carbon
double check with the frame that you get, some use IS42 instead of IS41 (park tool is a bit confusing by calling cane creek the "standard" and campagnolo the "proprietary"), there is also some oddball stuff like IS51
the crown race can be 36 or 45 degrees depending on if you get a cane creek headset or otherwise, you can choose this yourself unless your fork has an integrated crown race
bearing compatibility is pretty straightforward, you actually have some different choices like 30.2mm vs 30.5mm inner diameter for the upper bearing because the compression ring/wedge goes between the bearing and the steerer tube, the stack height might differ by +/-1mm affecting the size of the gap against the head tube
the stack height is counterintuitive with the height of the bearing because the chamfers are different, for example pic related is 8mm but probably has the lowest possible stack height, and the 6.5mm bearing has the same stack height as the 7mm bearing
