I have been running KDE Neon on my 10 year old laptop for a couple of years and I haven’t done anything you’ve mentioned here. KDE Neon gives you a notification when system updates are available and it’s just a mouse click if you decide to do it. No terminal involved.
As far as resources usages, it’s by far the lightest desktop among the “heavyweights” like Gnome etc. KDE used to be a resource hog in the past but it is not the case any more. In fact it has not been the case for a few years now. I installed latest Fedora Gnome last month and immediately went back to KDE because Gnome (or Fedora) took too much resources that the laptop was practically unusable.
I have also run Zorin OS in the past. The pro version is to get extra themes and customer support. You are not missing any functions in the free version.
