Nexogen is right about the red spectrum but that was back in the day of blue and red lighting - things have evolved a lot since and full spectrum beats any other spectrum.
The Ygrow will be better than the Indoorgreen one in my opinion as all leds are full spectrum, not just half and half supplemented with cheap red leds but for a hobby grower there will hardly be a noticebale difference, both are very good modern lights with some full spectrum to them.
You could argue the red bulbs will promote flowering more but overall light output would be reduced but that is just pure speculation as I have not compared the 2.
For a shelf I would recommend strip lights over grow panels as they distribute light in a shelf (ie long) manner whereas panels are designed for a square space so half would get wasted on shelves and the edges would not receive enough light.
Unfortunately the strip lights you have listed are not designed for orchids. They will work but they will not be built with the same quality LEDs, they will be designed for max illumination, you want some that are designed for max growth in plants and the quality of the LED makes a big difference there. 4000k will have more red than 6000k so the 4000k will promote flowering more.
I am sure someone from your neck of the woods will be able to recommend a good strip light for you
maybe you can get these
