Desktop Linux will always be in a state where it is great for technical users who have the expertise and time to fix and work around things. Because once you've done so, it is infinitely malleable. It will always be a miserable experience for non-technical users or technical users who don't have the time to fix the issues. Linux on the desktop only really excels when one party polishes the experience to be great and makes all the bit work togerther. E.g. like Google did with Android and ChromeBooks or to some extend Red Hat with Fedora (which is the best and most consistent Linux desktop experience).
Outside the desktop, little software is as successful as Linux. It's the substrate of the modern tech world.
Desktop Linux' success is like a hedge bet against Microsoft and OSX. It's just capable enough to be dangerous in a Mexican standoff between the three OSes.
Not to accuse you of shooting yourself in the foot, but a lot of these things are much nicer managed by complete desktops.
GNOME is certainly a tweak-lover's nightmare though, I'd recommend giving KDE a spin if you're brave. Qt applications and KDE should recieve fractional scaling support much sooner than GNOME (patch is already written/submitted), and generally the settings menu on that desktop is much more granular.
On the other hand, Pipewire has fixed so many small audio problems for me that I didn't even know I was having that I'm glad I switched over.
My biggest issue with Linux for mainstream is not Linux or its distros, but the guides online who are outdated, tell people to open a terminal for every little thing, tell people to add random software repositories that will definitely break something about the system within a year as a workaround without listing the implications, or are extremely condescending towards users.
Microsoft Certified Technicians and user forums will usually tell you to reinstall your OS every time an error shows up but at least they don't give detailed instructions on disabling all security on your computer, fucking up your bootloader config with a oneliner from 2009 that doesn't even solve anything or tells you to modify UEFI settings (like secure boot) for no reason at all.
People with no knowledgeable friends and family will find they get little support from help desks and other paid service centers and that's a big problem. Many normal people rely on external parties to help them with their computers when their printer decides to show some kind of error and computer service employees seem to only know Linux from their community college OpenSUSE server management course.
Back when I did helpdesk for a small ISP I had the occasional Linux user (often installed by friends or family because Windows XP stopped getting updates) and the problems I helped fix were all solveable by GUI settings and were documented in the internal IT knowledge base but still I got to do every single call because I "knew Linux". They did the same for OSX, whose users I also gladly helped to the best of my ability, but that's only because I bothered to Google and try because I'd never even seen a Mac. I've been gone for years but I don't think you'll get any support if you try to call that company with a Linux device today.
Strangely enough, this wasn't a problem for my coworkers when Windows released a new overhaul of all systems and settings. I remember when Windows 8 hit and everybody managed to sort out the terribly unintuitive GUI in a week.
My conclusion from this is that people have a very strange view of what Linux really is, based on something they've seen someone else do years ago. It's like basing all your opinions about Windows on someone managing a barebones Windows 2012 install through PowerShell. Several people were amazed when I showed them a screenshot of Linux running a GUI and the fact you could download Discord from a built-in software store blew their mind.
Firefox defaults to XWayland - you need to edit a setting to switch it to Wayland (MOZ_ENABLE_WAYLAND=1).
It's not unreasonable to assume Linux is bad, it's only unreasonable to assume nothing has changed since the last time you tried it. Make of that what you will.
