E.g. Cat B 804fpm and 655fpm on the outbound and inbound legs respectively.
Where can I find the regulations for this?
That is only for reversals or racetracks, it comes from Table I-4-3-1 in PAN OPS 8168 Vol2
Cat A/B 804 ft/min (245 m/min)
Cat C/D/E/H 1197 ft/min (365 m/min)
Cat A/B maximum 655 ft/min (200 m/min), minimum 394 ft/min (120 m/min)
Cat H 755 ft/min (230 m/min)
Cat C/D/E 1000 ft/min (305 m/min), minimum 590 ft/min (180 m/min)
The maximum descent gradients for the intermediate segment is done with the procedure design, they can go as high as 13.2 % if the speed is kept below 90 kts. The final segment depends on the type of approach, and if it has a FAF or not.

Then again, European circling radii are much larger than those in the US
You mean the FAA TERPS standard is more restrictive than the international ICAO standard.

I know for a Cat C aircraft it should be 1 197fpm on the outbound and 755fpm on the inbound leg of the letdown procedure, but can't find anything to prove it.
Close, 1197/1000 ft/min or 365/305 is for Cat C. Your numbers would work for a CH47 (Cat H), but not for a C47TP (Cat A).
