Oracle 23c comes with a new role called "DB_DEVELOPER_ROLE" packed with sufficient privileges for most developers on non-production systems, rather than assigning them the DBA role which violates the least-privilege security principle.
DB_DEVELOPER_ROLE role is packed with the following privileges:
CREATE TYPE
CREATE MATERIALIZED VIEW
CREATE TRIGGER
CREATE PROCEDURE
CREATE JOB
CREATE SEQUENCE

CREATE SYNONYM
CREATE TABLE
