I would +1 the zfs arrangement on this configuration as well. I am still
rather new to zfs filesystems, but my VM host is really happy with zfs. My
configuration using zraid and a pair of SSD's for storage tiering has been
very nice as a balance.
For a laptop that may meet your needs, I would suggest looking into the
Thinkpad T51g. 8 core CPU, Nvidia 2070 or 2080 graphics (nice to have
performance graphics without having to deal with Quadro prices), 4 SODIMM
slots, 2 thunderbolt, 1USBc connected to the GPU, 2 M.2 slots, a
fingerprint sensor, and various workstation extras. Let me know if you have
any questions as I happen to have one.

A mouse trap, placed on top of your alarm clock, will prevent you from
rolling over and going back to sleep after you hit the snooze button.
