Which power cable is suitable for parking lot lights and socket?

Just as a thought: perhaps consider [E-Ladestationen] and adjust the cross-section accordingly. As a precaution.

Then it should be at least 6mm2

For outdoor use, you need a cable labeled NYY-J

It is best to protect sockets and lamps separately. In your case, I would use 2.5mm². A 4mm² or 6mm² cannot be properly connected in any lamp.
The lamps will probably be LED lamps anyway, so they can possibly be protected with only 10 A or even just 6 A.

Cross-section depending on charging power and individually protected. A charging station has no place in a circuit with lamps or other sockets. Because charging requires three-phase current, i.e. a 5x Xmm².

Hello

can't you lay a conduit?
2 cables inside. 5x2.5 for the lamps and a thick one for the socket.
