I don't think science has determined this. GR is background-free, so in a
sense, space-time is a relationship between other things and nothing more.
It's not a "something" but an effect.

They're energy in the sense that they're mass in the sense that they're
mediated by particles (assuming one finds gravitons, at least). The electric
force is photons interacting with electrons, for example, both of which are
energy.

Actually, there's good reason to think information cannot be destroyed.
That's what lead to postulating the holographic principle and hawking
radiation. The basic problem is that the QM theories preserve certain kinds
of information that GR does not, so matter falling into a black hole
violates quantum mechanics in a very fundamental way.
I'm not sure I can go any farther than that. I'm not even certain you're
mistaken in saying information isn't energy, spacetime isn't energy, etc.
Just commenting on the bits I've vaguely understood. I can't really say I
understand it well enough to say yes or no on any of it. :-)
