Sans near-total embargoes on goods from a country, have we ever imposed sweeping tariffs of 145% on all goods coming from one of our most-imported trade partners?

No, no we have not. Certain tariffs were very targeted for specific reasons, you are correct. But those were not blanket-applied haphazardly at such high levels. Hence, "unprecedented".

We've had an infinity% tariff on all goods from Cuba for decades

Those are broader economic embargoes, not tariffs. A lot more is involved in that situation and it's much more nuanced than what's happening with tariffs today. Hence my comment, "sans near-total embargoes on a country". Tariffs are taxes on goods allowed to enter the country - embargoes are a total elimination of trade (meaning we can't receive and we can't ship to) with a country.

This is another apples/oranges comparison.
