I'm tubeless. I'm familiar with plugs but if that's not enough how should I patch it?
If you've got a puncture in a tubeless tire that won't seal with the sealant in the tire, and won't seal with a "bacon strip" insert (or equivalent), then you'll need to put a boot on the inside of the puncture. This can be a small piece of old tire, or you can buy premade boots with adhesive. After that, you either need to reinflate the tire using a compressed-air cartridge to pop the tire back into place, or use an innertube.
Putting a patch on the outside of a tube seems a lot less lasting than patching the inside of a tire based on the physics of it.
If you ever need to patch a tube, patch the tube, not the tire. The tube does the work of containing the air, and the tire provides the mechanical strength to contain the tube. If you have a puncture that goes through a tire and tube, and patch the tire (even assuming the patch sticks to the tire, which I'm not sure about), you won't be able to inflate the tube and keep it inflated. A properly patched tube will stay patched indefinitely.
