I'm sure there are some hotshot marketing/adwords contractors out there...and unicorns probably exist also.

If your small SaaS business can afford to hire them, then they aren't worth hiring.
I'm still not sure the theoretical consultants you've listed would be "good" as such. They'll just have a massive budget they can use to blow the competition away.
I'll rephrase it as: The "good ones" would be working in a completely different field where their talent actually provides some value to the world.
I'll be the first to say that measuring the incremental impact of advertising is often very challenging for a variety of technical and business reasons. That does not mean it doesn't work.
Where it doesn't work is when you have inexperienced people spending an amount insufficient to properly measure results, not implementing conversion tracking properly, using poor targeting, etc. Of course that's going to fail.
And I'll note that there are VERY technically-oriented people in the industry who seem to have no problem feeling confident that advertising works for them.
My problem is simply with people who have had a few bad experiences writing off an entire industry. All I'm asking is for a bit more evidence for such a sweeping accusation, which I think is more than a fair ask.
