I'm confused on whether I say:
Pepe es una persona buena
Pepe es una persona bueno.
(Pepe is a man, so I find the male/female agreement thing confusing when using persona)

Regardless of the sex of the person you are referring to, the adjective must always agree with the noun it modifies. So if "bueno" modifies "persona", and "persona" is a feminine word, the adjective must be also feminine.
Note that it is a common mistake (even for Spanish speakers) to mistake the "gender" of the words with the "sex" of the people. You can use feminine words to refer to male people (and vice versa), as in "Juan es una persona". You use "persona" (feminine) for a male person (Juan).
