Last time I checked,the thinking was that basically every galaxy has a supermassive black hole at the center.
Before they were able to photograph it, they were able to estimate its mass by observing the velocity of the stars orbitting it, which is a function of its gravity. https://yewtu.be/watch?v=XA7CAVm31z0
The nice thing about supermassive blackholes is that, unlike with smaller blackholes, you won’t get spaghettified as you approach the event horizon because the tidal forces are too low. But I imagine you would be fried by radiation or crushed by acceleration anyway and you wouldn’t be able to pop inside and hang out with the wormhole aliens like Matthew McConaughey in Interstellar.

You don't understand tidal forces and acceleration by gravity. If tidal forces won't get you, then by definition you won't get "crushed by acceleration". Tidal forces are the uneven pull of gravity. If gravitational forces are even, then you won't even feel acceleration (this is why you experience weightlessness during freefall). This is what inspired Einstein's general relativity.
I think youre right. How do you die then at the surface of a super massive black hole? Or do you? Assuming you could survive the heat and radiation of the accretion disc, I guess you wouldnt get crushed until you reached the singularity? Im not sure. Do you think you wouldnt notice a difference within your reference frame as you entered the schwartzchild radius?

You will be crushed eventually. You won't notice any particular effect when you cross the horizon, though your view of the outside world will change: https://www.youtube.com/watch?v=QqsLTNkzvaY
