Ubuntu itself is a performance hog due to snaps. And Ubuntu is NOT beginner friendly. As an ex-IT guy and as a linux enthusiast, It was not when I deployed it to developers and tech people in my company. And it is not beginner friendly when I install it to my friends & family.
I used to use Ubuntu for work until last week. Used it because of the worry for Ubuntu compatibility since most work related tools etc supports Ubuntu if you want to use Linux at work. It used to use 7.5-8GB ram and >40% CPU. So I switched to Linux Mint. It is based off Ubuntu but it is faster & is better for UX. And I have been using Linux Mint since monday. Ram usage wend down to only max 6GB RAM and <25% CPU usage. For the same workload. Since it is Ubuntu compatible, Linux Mint will support all those work related stuff for which they need Ubuntu for. And I have a lot of horror stories with Ubuntu.
I recommend Linux Mint if you want point release distro. It literally takes care of you and works OOTB. The only problem is it doesn't have wayland support yet. If you have the time to invest (which I think you don't since you mentioned tedious), and only if you have time, I recommend Arch Linux.
Another green flag is to prefer community led/oriented Linux flavours over corporate funded for long term UX. Way too many cuts and bleeds to trust a corporate run Linux distro. CentOS and Ubuntu being the latest ones. The only exception so far has been OpenSuse IMO. And I have heard good things about POPOS as well. I haven't used it to comment on it though.
I really see FreeBSD as my north star. But it is not yet there for my work and desktop usecases.
