Since there's going to be a lot of tiling WM users looking: what's the best way to get tiling WM and all the convenience of a "full blown WM like Gnome": things like Network Manager applet, bluetooth control, audio etc. all just few clicks away.
So, for example, disable xfdesktop and xfwm; enable other window manager of your choice. Then, when you run xfce4-session via any mechanism you get all of XFCE, but with another window manager. You can pull up xfce4-settings manager to handle all system settings as you would in any other XFCE session.
I am pretty sure that LXDE/LXQT allows this sort of modularity as well. I have no clue about KDE and Gnome.
Of particular note, you can combine XFCE's panel applet with a tiling window manager. So then you can keep an application menu and notification area (with associated notification settings) from XFCE with an arbitrary window manager.
It's not flawless. I had to patch plasma-desktop to get it to work at all, and there are still some bugs around widgets and toolbars I haven't found a solution for. But I'm still pretty happy with it. I have window animations with picom, and even window decorations that blend in pretty well, such that a casual observer probably wouldn't even notice that I replaced the window manager.
I'm pretty pumped that both Plasma and GNOME are now working on better tiling support by default. Maybe in a year I'll be back to using kwin or GNOME Shell.
One gotcha is that many full DEs use compositing window managers, which tilers usually don't. You can get around this by running a standalone compositor (such as picom).
In my case, I just have nm-applet for my networking needs, blueman for my BT needs, pasystray for my audio needs, secret manager and polkit started on login, etc.
The only thing I miss from Gnome is that fancy pinentry program that shades the screen, which is replaced with a basic gtk window.
