Map the cable path first
Start from the wall outlet and trace each device: laptop, monitor, light, speakers, charger, and dock. This prevents buying trays or clips that solve the wrong part of the mess.
Separate moving and fixed cables
Standing desks need cable slack that moves safely. Keep the desk-lift path separate from monitor and dock cables so the setup works at both sitting and standing height.
Use a dock only when it removes friction
A USB-C dock is worth considering when you connect several devices every day. If your setup is just a laptop and one charger, simple cable clips may be enough.
