We can confirm that Moana 2 has one credit scene to stick around for, which comes mid-credits. There's nothing post-credits so once the credit scene is over, you can leave without missing anything else.

Post-credits scenes aren't merely for the MCU. The new Disney animated film Moana 2, in theaters now, gets in on the fun of teaser bonus scenes with one of its own. Though Moana (Auli'i Cravahlo) and Maui (Dwayne Johnson) make it safely back to Motunui joined by the new communities they have connected with,

Moana 2 makes a clear point to address the 'is she or isn't she a Princess' debate after the first film with a fourth wall gag where Moana states she's "not a princess" to which Maui replies: "I know, but a lot of people think that you are." However, in the real world she is an official Disney Princess.
