Personally, I don't like the synthetic pads for carbon brake surfaces. You might try natural cork pads, instead.
Not all carbon rims are the same.
Cork pads will ruin some carbon rims (i.e. Reynolds).
On others they work best, and Swiss Stop yellows will ruin the rims (i.e. Bontrager). A big Trek shop I know regularly gets customers with rims ruined by Yellows because they listened to people on the internet rather than reading the manufacturer's documentation. Yet the shop owner got 17k miles out of a set of cork pads on Bontrager rims, which were not worn at all.
You need to know what kind of rim you have. Fortunately the rim maker does the research for you and publishes it.
For example, Reynolds says to use their pads and any others will void the warranty. They used to recommend SwissStop Yellow and Kool Stop Carbon before they came out with their own blue pads. The blue pads are far superior to the Yellows. The Kool Stops are even worse than Yellows- they are utter crap. They did not stop, squealed like a garbage truck and started chunking after an hour.
Black Prince pads are not quite as good as Reynolds blue (on Farsports rims, I have not tried them on Reynolds). They don't have quite as much bite and require a bit more lever pressure. But they are much better than the Yellows. I like strong brakes even though I am light and know how to descend- I do a lot of steep technical descents and stiff levers or brakes that need a lot of force give mu hands nerve pain at the end of a long day of climbing and descending. I'm used to strong brakes on motorcycles so I know not to jam them on in an emergency.
For aluminium I have used Dura-Ace, Kool stop salmon, and SwissStop black. The Blacks work as well as DA in the dry but not in the wet. They don't pick up rim shards like the DA pads do and wear faster. Salmons work as well in the wet as new DA and almost as well when dry and also do not pick up shards. But they wear faster although not as fast as the Blacks.
