I thought you were asking about klebsiella, not biolfims? Though of course it is smart to look into the films as well.
Turmeric is just a great all around herb with action against tons of pathogens. Definitely try it. There is something called golden milk? where you just boil up some turmeric in large batches with water and make a paste and then add it to milk, but you can add this paste to anything. I've done this with juices.
Your spice list looks good, try them all. But look into all of the eastern spices: cardamom, clove, ginger, black/white pepper, coriander, cumin, garlic (can be cooked if you react to it), asafoetida/hing (there was a recent post about it being good for roundworms), fennel, fenugreek, star anise, all varieties of hot peppers, cinnamon, etc etc.
I never had or treated klebsiella but I've seen enough links over the years about turmeric being good for it.
Biofilms are very complicated. Some of that complexity is that people mix and match the concepts of normal mucosa with pathogenic biofilm.
Try this for your biofilm: 3 bags of Lipton black tea in 3-4 cups of water, boiled down to 1.5-2 cups on empty stomach , add Sugar if you are ok with it.
Cloves are the highest ranking antioxidant food afaik. Foods high in polyphenols have broad spectrum anti-pathogen properties.
I didn't read what your metabolic problems are, probably it's very complicated.
Look into Iodine too. I suspect not too many pathogens can withstand direct contact with iodine.
