Relaxed Intensity
I like to split neotrad play between power fantasy, which is all about displaying competence / having cool moments in the spotlight and interpersonal / Slice of Life play, which is more about playing a defined character who often get themselves into as much trouble as they get themselves out of with a strong focus on interpersonal relationships. For the latter sort I think having mechanics that encourage playing to type really help because they can help overcome the need to focus on completing the scenario and give players cover to play the sort of character they want to play.
For my own play having things like Cortex distinctions, trouble aspects in FATE, Passions/Anxieties in L5R 5e and Nature/Demeanor in World of Darkness are immensely important because they help to overcome the trained impulses we all have, help us get a sense of each other's characters, communicate to the GM what sort of content players are interested and most importantly give players room to express themselves without feeling like they are letting down the team.
