Have you tried Mac OS ? It is probably more polished than distros and less enshittified than Windows.
Drito
IMHO distros share the same apps. The defaults can differ, the implementations too but the user can install apps that are on other distros.
I m not experienced but this video shows a way to use pass.

It is that software. https://www.passwordstore.org/ I still backup in an external dd but there are ways to store them online, like a git repository as instance.
I use Librewolf, I manage passwords with pass and rofi. Hoppefuly AIs will write a new FOSS web browser. I read here and here that the web standards are too big to be implemented by humans.
You can also install Alpine.
I customised Xfce a lot, only with menu settings. I removed the window tabs from the status bar, the focused window title is written on the status bar. The window manager was removed for bspwm. The result is an optimized screen space while keeping the convenience of a DE.
I use Xfce with a swap of the window manager by Bspwm. I got the easy to configure Xfce status bar (instead of things like polybar and others...) and also the Xfce terminal, file manager... The window title is written to the status bar. I use Super + B/N to switch the workspaces. Some apps are set to floating mode like the image viewer, the calculator... So everything can be displayed in a good tiling WM and I don't need to manipulate windows.
Redhat rewrites everything "not invented here" and put these things under "systemd" name. There are misundestanding between people that have political concerns, and people just happy to get unified shiny things. If one day Redhat provides a Systemd-OS I'm sure most people will be happy, and will shit on the previous system, with a separated kernel and the freedom of composing your own OS. Most people just wants an open-source Windows and I can understand that. But I also understand people that are ready to sacrifice some convenience to get a composable OS that can be maintained outside of big companies, thanks to simpler components
I installed Arch like that. When I had to do a new install, I forgot everything, then I used archinstall with Xfce option and it worked fine.
I prefer a glibc replacement.
