Sway and hyprland are going to be the main recommendations, especially hyprland because it is pretty feature-rich. I personally have been using River for the last few months, which I’ve been able to completely replicate my five year old bspwm set up with using the rivercarro layout. It’s not as popular, but I’ve really liked it so far.

I’ve used it on my pi before I disabled the display manager because I barely used it, but performance was fine. I could log in from my desktop, phone, laptop, another pi, anything really, which was nice to have.
