I mean, why not just straight-up copy Chicago95 onto Xfce and ship it distro-default? I don’t think it gets any more familiar than that
and it surprisingly works: Desktop alternatives - #25 by Espionage724
Everyone customizes the desktop anyway, but imo it’s more interesting to do something unique. I feel the DE shouldn’t be noticeable: I need to switch windows, and see what’s all open at once; I do both on GNOME with a Win key press or quick mouse-fling to top-left.
GNOME’s consistent: I do that flow any distro that has GNOME, therefore my flow isn’t distrupted regardless of OS.
GNOME’s minimalist: My flow works Vanilla no extensions; I can freely use any GNOME version and have a consistent DE any distro; probably even edge/dev. I don’t need to customize anything (GNOME stays unnoticeable), so I can freely switch OSs on-the-fly and be productive in GNOME instantly.
KDE offers every setting under the sun which is cool for customization, but I feel I have to change more from defaults each distro than I care for (some don’t enable desktop icons), and some defaults I don’t like particularly with the dock taskbar icons + hiding that I have to change. KDE’s fast-moving, and if there was a cli/config way to get some of that config reproducible, I doubt it’ll last long and I’ll have a whole page of dozens of em at some point. Basically I spend more time customizing KDE that’s unproductive.
Xfce is cool, but not unique. But customizing it is easy-enough to command-line consistently: I did that Win95 theme Fedora, openSUSE TW, and Debian with commands I made on FreeBSD 
Xfce can customize good, but I feel it doesn’t allow going far from having the traditional panel bar; anything more-fancy may be better on KDE, while anything less might be better going WM. Xfce’s good for the traditional look-and-feel!
More with GNOME’s consistency: I had the same UX on a phone that I did on my desktop, and it worked mostly as I expected! (could benefit from touch gestures) Having mainline Linux on a ARM64 Android phone is it’s own thing, but booting straight into a familiar copy-paste DE in portrait mode on a phone was impressive.
I later tried Xfce, and it was reasonably unusable
It was the full desktop UI, at my phone’s high DPI (tiny), with no touch/large-cursor accommodations. A stylus helped, but that wasn’t convenient.
I switched to Xfce because GNOME was unstable (random crashes to log-in mainly with using on-screen keyboard), but I knew Xfce had reliability with years of experience to do a better test on my phone (wanted to see if it was GNOME or something postmarketOS-related; was definitely GNOME).
Basically I like GNOME, and Xfce’s already available for familiarity!
