should it be tied to INTERVALS_PER_SLOT to take account for faster slots on e.g. gnosis?

Still better to try to propose. As long as it's less than slot time, it's fine.

this doesn't leave any time for the empty block to propagate, no?

What empty block? It's too late for any kind of local fallback, empty or otherwise, by this point. To quote https://nimbus.guide/external-block-builder.html
There exists a failure mode, intrinsic to the builder API, wherein the consensus client has signed a blinded proposal and therefore even if the external block builder relay or builder doesn't provide a full block, a consensus client such as Nimbus cannot safely proceed with step 2 and fall back on its local execution client.
"Safely proceed" == "without high risk of slashing".

ah, this is for when we've already signed it?
At this point, why not -- one can't fallback to a local EL anymore.
