Outside of the black hole, its gravity acts essentially the same as any object with the same mass—the Schwarzchild metric is used for the external gravity of the earth and sun too.
Spaghettification happens when there is a significant difference in curvature over the space containing different parts of the body. For a big enough black hole, the curvature at the event horizon can be gentle enough to be survivable for a human. There might be quantum gravity effects that change things but as far as GR is concerned, there’s nothing locally special about the event horizon of a black hole.

Has the firewall concept been discarded?
That’s a speculative quantum gravity effect, still a live hypothesis.
