With a long room like yours, I would recommend thinking about how you will use the different 'zones' of the room - so for example you may want something soft above the couch, enough to read by but also enough to relax under with a glass of wine in the evenings whereas over the table you may need something brighter for the kids to do their homework (or whatever your lifestyle lends itself to). Where possible I always recommend LED lighting - they are capable of producing both warm and cool light colours and can even be used in accent lighting. They are also very popular for their energy efficiency and they give off almost no heat which is an added safety feature.

I share you concerns with the look of the light. I lived in Cairns for a while and many restaurants etc had high ceilings with lights and fans with a more traditional look. Maybe you could do some internet stalking of hotel websites etc. I'd start with Palm Cove. Good luck.

your lighting plan sounds great and the floor is gorgeous but hope you plan to add some screening to the top of the fence and perhaps some tall bamboo or similar in narrow pots to help with privacy

I have similar lights on rear deck but shine light both up and down. 2 globes. And an overhead fanlight which we use while eating or playing games. The wall lights are great for softer lighting and are plenty to walk around. So I would put the right across rear facade. But make sure the switch for light in pool are separate to the wall lights in alfresco so you only turn on lights you want. With pool if you don’t have lighting in your pool you may want a spotlight.
