As I understand it, spaghettification only happens falling into a "small" black hole, the difference in gravity is huge over a small enough distance to stretch you into meat goop as your corpse fall towards the singularity.

A supermassive black hole like in our and most galaxy centers, you'd cross the event horizon without noticing anything different besides tunnel vision. But yeah. It'll end with total obliteration.

Makes sense tho, there's not much complexity to the material expanding from the big bang initially. Squished into almost nothing and squirted out the other end completely unmade is not great sci-fi :(
