What does HackerNews think of wl-clipboard?
Command-line copy/paste utilities for Wayland
There's wl-clipboard with the commands wl-copy and wl-paste: https://github.com/bugaevc/wl-clipboard
Works flawless in my experience.
I spent a little while on this, but I migrated from i3, so I just ported every little section of my config bit by bit.
In terms of battery bar and other "bar" type things, I use waybar[0] which basically does all the things you'd expect by default (just install and it "works").
For multi-monitor, config, I initially setup with wdisplays[1] (think arandr for wayland) and then manually copied the positions into my sway config. Monitor positioning was the only thing I needed to setup (and telling it that one monitor was HDPI) and then all of the scaling and everything worked perfectly. This was my biggest selling point for wayland, I now get nice crisp fonts and application scaling works nicely (which was not the case with X).
volume control from the keyboard took no time, just a couple of extra lines.
There was some stuff to do with the clipboard (wl-clipboard[2]) and screenshots (grim[3] + slurp[4]) that required some setup, but again, just a few lines, and didn't take much mental load.
Oh and I needed to change my notifications daemon(dunst[5]), and chose to change my program launcher to one with a nicer interface and cleaner fonts (wofi[6]).
I think that's all the tweaking that I did. Oh, and I needed to do something with pipewire to sort out screensharing at the start, don't remember that too well though...
