You know what the excruciatingly missing piece to all this is?
Documentation. Not the BS that passes for documentation these days, I'm talking "For Dummies" level intro material that tells you, in English, what all these things do, what they're intended for, stripped of all the marketing hype. Even, dare I say it, an "index of indexes" kind of document, that lets you quickly narrow down exactly the kind of services you might need.
Then once you've done that a nice, straight-forward set of documentation to explain (not just MS-style sound bites) what processes you need, how to implement them, what gotchas to watch out for, etc.
But of course writing good technical documents is something of a lost art. It's hard, it's tedious, it's expensive, and it "slows down the developers" who are haring off after their next fever dream.
Which means the rest of us are left foundering, trying to decipher ancient Babylonian texts without a Rosetta stone!
