Welcome to Linux Questions!
You're asking us to look into a crystal ball! No-one knows what the job market will be in the future.
However, I notice that quite a lot of Sys Amins/Programmers and other computer people (on the Linux/Unix side) appear to be on the, shall we say, "older" side.
I'd reckon that there's likely to be a need for "new blood" to take over when the older generation retire.
I'd reckon that the courses you mention, plus associated experience would hold you in good stead.
Go for it!
