My rhcsa expired and I only have experience beyond that. Your task right now is to find a job and the easiest way to do that is to leverage your network. If you don't have a network, you need to prove that you can commit to a long term plan and learn a skill. Most people do that with degrees. Unfortunately a lot of people have degrees and technology is getting more competitive. That's where you see school competitions and certifications. If you don't want to do that, you'll need to be able to speak competently to the role.
Unfortunately right now I do not recommend platform/devops/sre for anyone breaking into the field. If I create an application today, it's server less or bring your own dockerfile on a provided machine image. So what are you administrating? Legacy shops will be around for decades, but the future here is layered architecture not os tasks.
