FDR was nothing like Trump. He broke norms, yes, but he was also held office during two of the most dire existential emergencies in the history of the United States: the Great Depression and World War 2. He did unprecedented things because he lived in unprecedented times.
And, crucially, he did them to preserve the Constitutional order, not to overthrow it. Unlike most of his class, he was cognizant of the fact that if the government could not organize an effective solution to such a deep crisis, the people would eventually rise up and replace it with one that could. He wanted to stave that off. He took drastic measures to deny oxygen to those would have taken even more drastic ones.
(There is one thing on your list that is universally held to be unjustifiable today, of course: the internment of Japanese-Americans. And I would agree that it was unjustifiable, even under the circumstances, which were grave. But there are decent arguments for the other ones.)
A good analogue to FDR's unique situation is Abraham Lincoln, who is really the only other President to have faced similar crises. Lincoln did things under the rubric of the Presidency's war powers that go right up to the red line (and, some would argue, beyond). He locked up political opponents who espoused support for the Confederacy, and denied them their habeus corpus rights so they couldn't get out again. He imposed the first involuntary draft in American history. When Maryland threatened to secede and cut Washington, DC off from the rest of the North, he clamped down martial law there, hard. But he did these things to preserve the Constitutional order, not to wreck it.
If you want a character from FDR's era who resembles Trump much more closely, go check out a few books on Huey Long, who was exactly the sort of figure FDR acted in order to head off: https://en.wikipedia.org/wiki/Huey_Long
