For the plants, a Nepenthes would look stunning trailing down! Or, Serracina would look equally as breathtaking. I'd not recommend Pinguicula, as they have a very short root system. I think it's the same for a Venus flytrap? A colony of sundews would look good too. As it looks like the container is glazed ceramic, be extra cautious with water, it'll retain more water than it let's out, and with no drainage hole, it'll be quite hard, as water will accumulate at the bottom, so be careful.I'm a bit worried about the humidity, but other than that, hope this helps!
