For now, my temporary solution is to use my 14" MacBook Pro with a couple of external monitors (glad I bought that OWC Thunderbolt 3 Dock). Problem is, the camera I use for video calls is mounted on my iMac. Since my long-term plans are so unsettled I decided to just slide the carcass of my dead iMac back a little bit and put one of my external monitors in front of it.
The iMac is effectively serving as a very expensive camera stand.
