5 pin connector recommendations that have both male and female sockets available (programming.dev)

I'm looking for a 5 pin connector type that I can easily find chassis plugs for both male and female.

I've looked at DIN and mini xlr connectors, but have unsurprisingly been unable to find male chassis sockets.

The pins needs to support 12V 10A*

*realistically only expects about 6-7A flowing through 1 pin and one fourth of that through the 4 others.

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.

Edit: I should have clarified that the 4 pins "leading to earth" are connected to mosfets controlled by PWM signals, so they aren't directly connected to earth. Each of the 4 pins carries a unique amount of current. Their total current is flowing through the fifth pin. Sorry for missing out on that detail in the original statement.

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 per pin depending on the connector 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)
