I picked up a OWC Envoy Express Thunderbolt 3 SSD Enclosure.
You can buy one directly from OWC for $79.
OWC Envoy Express Thunderbolt 3 Bus-Powered Enclosure for M.2 NVMe SSD
I plan to use this enclosure along with the Samsung 2TB 970 EVO Plus NVMe M.2 Internal SSD to roll my own massive fast external storage solution for my MacBook Pro 16.
My goal is to be able to edit 4K video with Final Cut directly on the disk.
