I heard that there are Mitzvos that forbid certain behaviors toward fellow Jews but allow or prescribe those very behaviors toward gentiles.
What are some examples of such Mitzvos?

Lending with interest for one: "You may not take interest from you brother, neither interest on (a) money (loan) nor interest on (a) food (loan); You may take interest from the foreigner..." Deutoronomy 23:20-21
Another two examples are:

Here's a funny one from the very end of the Gemara Meghillah:
אָמַר רַב הוּנָא בַּר מָנוֹחַ מִשְּׁמֵיהּ דְּרַב אַחָא בְּרֵיהּ דְּרַב אִיקָא: שְׁרֵי לֵיהּ לְבַר יִשְׂרָאֵל לְמֵימַר לֵיהּ לְגוֹי: שִׁקְלֵיהּ לַעֲבוֹדָה זָרָה וְאַנְּחֵיהּ בְּשִׁין תָּיו שֶׁלּוֹ. אָמַר רַב אָשֵׁי: הַאי מַאן דִּסְנֵי שׁוּמְעָנֵיהּ — שְׁרֵי לֵיהּ לְבַזּוֹיֵיהּ בְּגִימֶל וְשִׁין, הַאי מַאן דְּשַׁפִּיר שׁוּמְעָנֵיהּ — שְׁרֵי לְשַׁבּוֹחֵיהּ, וּמַאן דְּשַׁבְּחֵיהּ — יָנוּחוּ לוֹ בְּרָכוֹת עַל רֹאשׁוֹ.
Summarized, you can tell an idolater to shove his idol up his “wild donkey”, and call someone who hooks up too much a son-of-a-[sn]itch.
You can't insult a Jew like that.
A very simple rule of thumb for all of those rules.
Anything a gentile is not forbidden in the seven Noachite laws from doing to a Jew, a Jew is likewise not forbidden from doing to a gentile.
For example
A gentile may charge interest to a Jew. A Jew may charge interest to an non-Jew. The laws of interest are internal among Jews.
A gentile may not deceive a Jew. A Jew may not deceive. The prohibition of deception is universal.
A gentile has no Torah obligation to return the lost item of a Jew that he found. Similarly a Jew has no such Torah obligation towards a gentile.
The above is on a Biblical level. Due to the behavior of non-Jews in certain areas things may differ. For example while there will never be a biblical commandment to return the lost item of a non-Jew in a place where non-Jews are very careful to return lost items and the local law requires it would not be so simple for a Jew to keep the lost item of a non-Jew on a rabbinic level either.
Considering Chullin 115b - Although the Nevelah prohibition [Devarim 14:21] would allow "perished" livestock to be sold to Ger & Foreigners, the Orlah prohibition [Vayiqra 19:23] would not allow farmers to sell the "withered" fruit from 3-yr-old trees to Foreigners, since [Chullin 115b:8] forbids any (nutritional or monetary) benefit.
