Best Certifications

Hey all, college junior year currently in the process with multiple REPE and brokerages. I feel that I have developed my candidacy for these jobs pretty well over the last two years, but as I approach the workforce I have begun to wonder about developing myself not only to get the job but succeed at it. A question I bring up at the end of interviews is what would best prepare someone to add value day 1, or being more realistic within a few weeks or months, and I get the common answers of modeling courses. I was wondering what is the best modeling course for the price, but also are there any other niche skills or courses that an analyst could have today that would make them better at their job like an AI course or general market knowledge courses like bloomberg certs. All advice is greatly appreciated.
