Suggestions return pump for 265 gallon.

Internal or external?
 
Contrary to popular belief you don't need 10x or more flow. You could get by with 4-5x and that would give you 100x per day tank turnover. That being said, the COR 20, anything in the Vectra, and any reef octopus pump are all known as very high quality DC Pumps. They're quiet, very controllable, and popular for their build quality. Price is high, but the return on your investment is worth it.
 
When I had that size tank, I used an Eheim I believe 2612 but then went to a very quiet and easy to clean Sicce 4.0
