The season features prominent diversity in characters, including the first Asian-American Muppet Ji-Young, autistic Julia, Abby's step-brother Rudy, and a diverse human cast like Cuban-American Nina (Suki Lopez) and child Charlie (Violet Tinnirello from a military family), alongside puppeteers from queer, Iranian-American, Mexican, and Brazilian backgrounds. Storytelling integrates inclusion themes, such as modifying pickleball rules for Rudy's participation, overcoming fears for group events, and a Mitzvah Day kindness project.

Notable progressive touches include celebrity guests like non-binary Jonathan Van Ness in 'No Wrong Way To Be You,' where characters explore hairstyles to affirm self-expression, lesbian singer Reneé Rapp, and a Martin Luther King Jr. Day episode with Michael B. Jordan. These elements noticeably shape character arcs and plots around identity affirmation, resilience through feelings-talk, and social connection, extending Sesame Street's long history of diversity but amplifying contemporary identity politics and SEL without dominating the core puppet fun—though it contributes to broader audience backlash labeling the show 'woke' for such inclusions.
