Buono vs. bravo
In Italian, buono and bravo can both translate to good, but they are not interchangeable. The key difference lies in what kind of goodness they describe: buono refers to an intrinsic quality, while bravo refers to a skill or good behavior.
Buono
A1Buono describes the inherent quality, taste, or character of a person, food, or object. It relates to something being genuinely good in its nature, kind, tasty, or of high quality.
Questo vino è davvero buono.
(This wine is really good.)
Maria è una persona molto buona e generosa.
(Maria is a very good and generous person.)

(I bought a good book to read on vacation.)

(There is a good smell coming from the kitchen.)
Ti auguro un buon viaggio!
(I wish you a good trip!)
Sii buono, non fare i capricci.
(Be good, don't throw a tantrum.)
Bravo
A1Bravo describes a person's skill, ability, or commendable behavior in a specific context. It is used to praise someone for being talented, clever, skilled at something, or well-behaved.
Quel cantante è molto bravo.
(That singer is very talented.)

Summary
In short, use buono for the quality of things (a buono pizza is tasty) and the kindness of people (a buono person is kind-hearted). Use bravo for skills and behavior (a bravo student is clever; a bravo child is well-behaved). A pizza cannot be bravo, and while a surgeon can be a buono (kind) person, you hope they are also a bravo (skilled) surgeon.
