As a ThinkPad Z13 user, I've had none of the issues you've described. I've been running Linux (Fedora + Arch) on it for three years now and it's been a first-class experience. Everything worked out-of-the-box, with literally zero issues. I can't think of a single thing that I'd want to improve, from a laptop user's perspective. For me, this is the definitive Linux laptop experience.

I had a similarly good experience with my previous laptop, an HP Elite Dragonfly. Only niggle was that not all bits of firmware was upgradable via fwupd, so I had to ocassionally boot into Windows to do the firmware updates. But other than that, I don't recollect any issues with it either, suspend/resume/power management all worked as good as Windows. In fact, battery life was better than Windows when I applied powertop's tweaks.

And I'm sure the laptop experience is equally good on "native" Linux laptops, such as the ones from System76, Slimbook, Tuxedo etc.

So personally, I wouldn't make a blanket statement like "I wouldn't recommend it for your laptop unless you're an enthusiast". To be clear, I'm not claiming that the issues you describe don't exist, but at least for laptops known for having official support for Linux, the experience should be good.
