MSP's are great for learning and utilizing new tech in various orgs doing various things. it is great to get a broad spectrum of tech and all its eccentric uses
I would harp on learning and utilizing tech that works within your job role.
A good way of quantifying these skills would be certs.
eg .. Azure Solutions Architect, AWS Certified Solutions Architecht , VMWare, citrix, etc ...
Make your goals reasonable and obtainable !
I would put the first one as understanding the goals, structure, and intricacies, of the MSP you work at.
