I mostly recommend RHCSA and RHCE at the very beginning of Learning step, which gives you System Adminstration skills.
The course name RH124, RH134 which gives you basic understanding of Linux in a systematic way also helps to earn RHCSA title by giving exam.
Another course name RH254, after completing RH124 and RH134 it is understood that you have some basic knowledge of Linux. Now move ahead with knowledge of Server-Desktop architecture with course RH254 and earn RHCE title after exam.
What next after achieving RHCSA and RHCE...?
There are plenty of courses available, select them according to your interest and passion.

Yes, I would agree to this. I'm in the running to get my RHCSA. But in my previous job I was able to get a lot of linux experience. But it would have been nice to do RH124 and RH134. I think that would have helped me more and faster to understand linux.
If you are ased by someone how to begin with Linux (and they've never touched Linux), point them to this free Red Hat Course:
30 days free access
It's catagorized as an introduction to Linux, but if someone were to actually go through that entire course and practice it, it's a decent foundation.
Anyway, it's a good resource to share with those who are very new to Linux
I believe that automation is of paramount important to any SysAdmin, and therefore Ansible training should be pursued - specifically DO407.
One learns lots of important, but manual, tasks in the SysAdmin courses, but it doesn't scale well. Learning to automate operations would be the next logical step.
How about the following for a starting point?

RHCSA and RHCE are of paramount importance to get to know Linux. After that, as you mentioned it depends on what yolur focus is and what you're looking to do. If you search for RHCA (certified architect), there are a number of paths such as cloud/devops/datacenter that can take you in the right direction.
What's next after RHCE? I think that depends on what skills you're looking to grow.
DO407 Automation with Ansible I - Ansible is becoming a fairly important systems administration skill. The content here allows you to better operationalize your machine management. I'd describe it as taking those System Admin skills you've learned in RHCSA/RHCE and now learning a tool to run them at scale (instead of on one or two systems)
RH442 Red Hat Enterprise Performance Tuning - This class spends a lot of time going into additional tools that allow you to gather data about running applications, processes, the kernel, as well as adjustments that can be made to optimize the machine for specific work-loads. Personally, I've used the tools and approaches from this class many times to help determine why applications or updates have caused a change in behavior on machines. I've found that often, application developers don't know the actual OS stuff that their applications are doing. If they mess something up, they rely on the systems administrator to be able to tell them what is happening on the OS side, so that they can determine where in their application they need to focus to try and troubleshoot and resolve the issue.. Generally, the class discussed a lot of the lower-level OS activities that are occuring to the system and why one might care about them.
RH403 Red Hat Satellite 6 - Enterprise Red Hat environments often use Red Hat Satellite as a management tool for controlling updates and a variety of other system management/entitlement management tasks.
RH436 Red Hat High Availability Clustering - This class mostly focuses on the additional software Red Hat offers for running a highly available cluster and configuring cluster services. It is an add-on Red Hat product that runs on top of Red Hat Enterprise Linux.
RH415 Red Hat Security, Linux in Physical, Virtual, and Cloud - A relatively new class, but one that takes over for RH413. The focus is on security practices, and specific configuration to comply with some requirements for common security policies. These are best practices for systems administrators and something they may be requested to work on in various environments that comply with specific security compliance standards.
