Uses for palm fronds and branches?

I have access to a good amount of fallen palm branches and am wondering if there are any good resources for using them as a construction material or other uses. I gathered a bunch after some heavy winds last night, planning to use the fronds for mulching or weaving and the branches for garden building materials: stakes, lattice, support, etc.

I’m wondering if there are other common uses I might be overlooking, especially for the reddish-brown curvy part that connects to the trunk. Is there anything practical to do with this part or should I just put it straight into the city compost bin?
