Is there any good decentralized cloud storage for personal backups as a self-hoster?

No. Why do you think it is?
"Cloud" infers centralized consolidation of resources in a datacenter. A PaaS, for example.
"Decentralized" infers any number of running instances of something that are not tied to any specific vendor, infrastructure, or location.
Cloud can be distributed, but not decentralized since the underlying controls of the infrastructure are themselves centralized.
"Cloud" simply means it's on other people's machines.
That is not what that term generally means. Somebody COULD be running their own cloud platform, but if you're speaking to a large group of people and you say "Cloud deployed", they understand that to be deployed to a Cloud Provider on a secured platform and location (AWS, Google, Azure...etc).
We don't say "cloud" in engineering anywhere without meaning this. We may refer to a non-colocated deployment of something as "edge" or "off-site", but never "cloud". There isn't a single engineer on this planet who would ever confuse "deployed to cloud" to mean somebody's basement.
The name cloud comes from depiction of "somewhere on the internet" in network diagrams. I don't know what corporate environment you're in but you're using the term incorrectly.
Lol, okay, bud. Not only are you absolutely wrong and seem to have no professional experience with this whatsoever: search engines, engineering blogs, Wikipedia, history, and every other known source of truth on this disagree with you, yet here you are arguing anyway. Amazing. 😎
Thanks for the Wikipedia article. Can you quote or paraphrase the first sentence?
I've heard of some blockchain based systems referred to as decentralized cloud before (including stuff like Sia and Storj, which I guess is what OP wants). I haven't looked into them that much, but IIUC they push most (all?) controls and so on to the edge. I'm not sure I'd use them though since the networks aren't super large.
I had the impression cloud was about the opposite - detaching your server software from physical machines you manage, instead paying a company to provide more abstracted services, with the ideal being high scalability by having images that can be deployed en masse independent of the specifics of where they're hosted and on what hardware. Pay for "storage", instead of renting a machine with specific hardware and software, for example.
