If I'm routinely going off-road, I want to stick to relatively known trails. I'll save scaling mountains for my holiday.

What's normal? Normal HN reader? Probably Debian-nonfree, which has all the good parts of Ubuntu and almost none of the bad. Soccer mom pinterest poster though? Windows or Mac.
IMHO, Linux on the desktop is still for those with an above-average interest in computers. Hardware support is getting pretty damn good and software support is great, provided you know about the FOSS options. However, you're also pretty likely to run into some kind of snag that you will either have to just tolerate, or fix yourself by gradually learning how to poke about in the terminal.
Openness leads to diversity which inevitably makes standardization harder. Thing is, I prefer that to the ever-increasing user disempowerment in Windows and MacOS.

They'll use Wi-Fi or USB tethering with their phones for internet browsing and my dad will occasionally connect the laptop to the TV set to watch some videos, and it all just works.
There are problems with Windows and Mac for casual users too, but it'd be sugarcoating things to say that Linux isn't far more likely to spuriously act up.
The people who have trouble are the power users. None of the more advanced tricks work anymore, everything is different and weird, and they dont want to relearn from scratch.
Essentially it's ubuntu 18.04 but KDE packages are from the KDE team.
