My recommendation is to design and create your own labs/projects from scratch. For example, for Security+, I have designed 5-6 projects spread across a semester to build up students' hands-on skills, in addition to CertMaster labs. Project 0 involves students building their hacking lab in virtualbox/vmware, then subsequent projects use that environment to build their skills. I aligned the projects with various phases of the cyber kill chain. I also require students to participate in a CTF competition. You can draw inspiration from various books and online platforms, as well as leverage AI, if you need help with coming up with ideas for the exercises/labs.
