Permanent Christmas lights, anyone with experience?

A contractor friend is building a house, I’m wiring it trade labor. They would like permanent Christmas lights on the gables.

For rough in, I was just going to run low volt 4wire to all the corners and drop them in basement by their other drivers and put a switch somewhere.

Is this what people are doing? Is ribbon not the product I should be using? Are there line voltage options?

If it is ribbon… weather proof coated or weather proof channel?

Point me in the right direction, thanks
