prop advice needed pls

I got these cuttings from someone who forgot to water this guy for a while. I’ll let them callous before planting.

My question is about the length of cuttings. I’m familiar with propagating tropical plants—in a case like this, you wouldn’t want to try to prop such long pieces (esp indoors in the winter), you’d cut them smaller.

What’s the best size to cut them to? For the ones that have “branches” (for lack of better term), is that ok or should they all be single strands? Do they have to have a natural “end” or can the end also be a cutting?(I hope that makes sense)

(To be clear: this is a trailing plant that was in a hanging basket and the longest pieces are 5’)

Thanks so much!!
