As people have said the literally one example of Marx being "racist" against black people is the one letter where he uses the German word that also translated to "Negro", which was the contemporary term for black people
Here's a summary of "On 'The Jewish Question'" I saw recently that was good:
On The Jewish Question moves between summarizing the original Bruno Bauer Essay and then responding to it. So there are moments where if you're not aware of what is happening you might thing he is endorsing anti-semitism. But then he turns around and shoots the arguments down.
You can think of the essay as coming in with two parts. One being the Jews aren't free of they are given their own laws by the State. Or that they have a political distinction as Jews. But as Marx writes this distinction of being Jewish, when the State identifies as something else (Christian) renders the Jew an eternal guest at the mercy of the Christian State. So for the Jew to be politically emancipated the State must necessarily have no identification with X or Y thing.
The next is the emancipation of Judaism as a social relation, which comes with its own issues of stereotypes associated with Judaism. To be Jewish is to be associated with, or made out or made to be a greedy Jew. So the social emancipation of being Jewish is to liberate the idea of Jewishness from this, so the Jew may freely associate with their Jewishness free of stereotype.
Where as in Bauer's arguments the Jew is free if they abandon Judaism and convert, or the State makes atheists of all men. But as Marx says enforced atheism or state enforced anything replicates the same sort of oppressions as before. So the solution is a state that does not identify itself with an identity, and an identity comes to be free of preconceived notions.
tl;dr - "Bauer, du hast cringe posten." -Marx
What Marx was legitimately bad with was Orientalism. His stuff on the "Asiaticmode of production" is rather embarrassing
I don't know that I would characterize Marx as orientalist (his theory isn't orientalist in the slightest, much to the chagrin of Edward Said), but he definitely did not understand east Asian societies. Engels wrote about this later in life once more information became available to European historians. Most of what Marx thought about Asian societies came from Hegel, e.g. in the Philosophy of Right, which was so deeply flawed as to be useless.
To be fair, given the "totally not doing an opium genocide here guys" propaganda of the time, it's hard to see how he could have been right at the time without literally going to east Asia for a decade.

He's also writing it in response to anti-semites hiding under the guise of socialism in Germany
