Interesting question.
I tend to maximize every device I own. As a result, but in summary, I've installed nearly 100 apps in my last Windows Phone (Lumia 1020), systematically arranged in folders which give me both only the information I need at a glance but with the option to dig for more when I needed to. It was performing everything I wanted a phone to do, and even more with the "universal relationship" it had with my Windows 10 PC. But the 1020 was aging, and without hearing any news about a new device that would be the successor of the 1020, I switched.
The switching gave me a fresh look and retrospective on what a phone really is. I had the impression that Windows Phones and Windows 10 Mobile was, is, and could be trying to do more than what it is supposed to, giving the illusion that it is more than what it is. Now I have a device, in comparison, that can do everything I need a phone can do - and here's the key difference - without making me rely on it too much nor making me hope and believe that it can do more, that it will eventually grow into something more.
But back to your question. Given the usage you've listed, Windows 10 Mobile wouldn't disappoint. It didn't disappoint me. But, as always, it is when expectations exceed the boundaries of capacity, design, and purpose that disappointments start rushing in.
In a subtle way, the "illusion" I was referring to is probably the root of the disappointments reported elsewhere.
