Led lighting running on both sides of each of the beams - you can buy it in strips. I would go for a bright white but you can even get it in colours and or changing colours. I would also do the same along the floor under the cabinets and perhaps between the upper cabinets and bench top.

How about something like the below up and down wall lights in a black/dark charcoal. Up and down beams can be adjusted and when lit at night, they will show off beautifully the linear cladding.

Well done its going to look beautiful! I would consider have both! Even if you have the wall light above the bed a lamp beside you will act as task lighting for reading at night, whereas the wall light is more for lighting the room itself. Find lighting that compliments each other or from the same range for a cohesive and subtle look.

Um why ? I'd do a coffee table , and have the light maybe 1 metre or less from the ceiling . The second one I'd just balance the first one , so if the first one is say 2.5 metres from one wall , hang the other 2.5 metres from another wall . The lights are really nice -- you would want them to be seen , rather than highlighting a couch IMO .
