Labs, course, program etc for Linux sysadmins

Hello, I'm currently in IT working with identity management (totally different from linux-sysadmin). But I have been using linux for years personally on my laptops, servers etc. and I really enjoy it.

As I dislike my current job a lot I want to improve my linux-skills and generally sysadmin-skills I wonder if you guys know any labs/courses/programs/educational websites where I can improve Linux sysadmin-skills, networking, ansible etc. I do spend lots of time doing various stuff from internet, youtube, sadservers etc but I would rather like to follow a program or a course that is good in the way to explain and with labs to practice what you've just learned. Kinda like TryHackMe, PortSwigger, HackTheBox and these sites but specifically for Linux sysadmins.

I appreciate any tips. I'm willing to pay for some platform if it's highly recommended and contains solid stuff.
