For entry-level students, I found the MTA exam materials a good start for getting a win. For being able to study multiple areas without having to go too deep and maybe not passing a big cert. As an instructor for CompTIA, I would provide students with MTA learning materials and practice exams to cover topics covered in A+, Network+, Security+ etc. to get more of the MS angle.
The MS role-based Fundamentals exams are the evolution for that step as the MTA exams retire. I am not a fan of the MCSA/MCSE retiring at all though since I feel that on-prem is here for a while still and that employers still hold those certs in high-regard for employment.
