It's been years since I had to admin Windows servers, but I was quite impressed with the number of MS products where the install and configuration tools would output the Powershell commands to carry out the changes you'd asked for. It made it quite a lot easier to automate. I'd love to see that paradigm catch on more widely, with the GUI and CLI having the same functionality and the GUI giving you the commands to run.
I use a little oneliner with tofi (rofi/wofi would also work) to select the current output and avoid pavucontrol. It's mapped to a sway binding but would probably work in any wm/de:
pactl set-default-sink $(pactl list short sinks |awk '{print $2}' |tofi $tofi_args)
I'm using pipewire so the functionality of pactl is actually provided through pipewire-pulse I think
