For me, "I ship it" means "I enjoy the idea of these characters together" or "I think these characters have a dynamic I'd like to see explored in canon/fanworks/both". I share most of your meanings, apart from the "I have trouble enjoying fanworks where they are not together". That's a meaning that hadn't really occurred to me before.
