Any non obvious product you can suggest me to purchase and improve my home office?
Alternatively a good electric desk like a Jarvis or Uplift, or Ikea's Idåsen.
A good desk lamp that can project diffuse light onto your face for meetings. Combined with a good 1080p camera that sits high. E.g. Logitech C920S. Not a low-res up-your-nose laptop webcam.

Also, you’re going to want a good microphone. Blue (now owned by Logitech) and Røde make good USB-connected microphones you might want to look at.
Do some research on what it takes to put on a good YouTube or Twitch stream, and those products are likely to also work well for doing regular video calls for business.
