Comment on 5 pin connector recommendations that have both male and female sockets available

10A is a pretty big ask. You might want a few more pins to spread that current around. What are you other pins used for. DE-9 is where I would probably start.

I don’t know how aging affects the LED power draw, according to the manufacturer I shouldn’t expect more than 7.5A. When measuring peak power output, I get only get ~6A total though.
4 pins are for earth with each (measured) having ~1.5A going through them at peak brightness. The fifth pin must bear the total load of the four other pins.
Having 5 pins is of course not a strict requirement, it’s just the LED strip that has 5 connections.

If you solder together the ends on the LED you’ll only need 2 pins

By soldering the ends of the LED, do you mean the 4 earth connections? I should probably have clarified that the 4 “earth” connection only lead to earth when the mosfets connected to the LED is open. Each connection leading to earth is for either, R, G, B or W so they can’t be soldered together.

You could use XT60 connectors and connect together the ground pins

Sorry, my original comment was poorly written. While they do lead to earth, there is a mosfet in between each that receives a unique PWM signal. See the edit for more details.

You could use something like a dsub connector with larger current carrying pins (more expensive) or a more regular connector (e.g. 15 pin dsub) with multiple pins for supply/high current.
Regular rectangular headers can handle anywhere from 1-5A so you might be able to get away with a 2x4 rectangular header (maybe a few more pins in parallel for everything just for insurance)
