But the short answer is if the Lighting plugs in, you plug it into a smart pocket socket or an RGBW controller if you want color effects. If the lighting works on a switch, you just find a smart device to replace that switch. If the lighting is battery operated, you need to choose one that has a remote that you can then automate.
And some people use spots from underneath that plug-in, like the Hue blooms or something similar.
I think LED strips are probably the most popular, but they can get expensive.
It just really comes down to your own aesthetics, any of these can work technically.
