Xfce has long been the only DE that gets out of my way enough for me to actually be productive instead of excited by the possibility of different configurations.
The main tiling window manager using Wayland is Sway, although personally I like the simplicity of DWM. You can easily edit the configuration and compile it yourself.
One of the things I love about XFCE is its modularity. It's literally just a collection of programs that work independently, so while I use DWM, if I need a panel, I just type "panel" into dmenu, and XFCE panel runs right on top of it with no problems, aligning perfectly over the DWM top bar.
If you want to try a more complete DE, I'd recommend COSMIC. It's fresh and fast and very customizable.
