Question: Do any of them offer actual privacy or refusal to feds if you don't run your own server, node, etc.? Which is better for a pleb with no self-hosting?

Wasabi is designed in a way that the client does not trust the backend. No sensitive information is ever revealed: no xpub, no IP, no common input / output, etc.
Even if the wabisabi coordinator is run by an active adversary, the client should protect you. (those are bold claims, Wasabi is still WIP, and this architecture goal is bloody difficult to build)
