Thanks for all the advice.

How does one use a discarded NVME SSD drive ?  If it is SATA, put it in an external enclosure ?

There are 3 common types of SSD drives, NVME and SATA NGFF (Next Gen Form Factor?) that
use M.2 slots, and legacy (OGFF?) SATA.  There are enclosures for M.2 NVME and SATA, for the
M.2 SATA NGFF drives you may need an adapter.  I have <https://www.amazon.ca/StarTech-com-Adapter-Converter-Housing-SAT32M225/dp/B00ITJ7U20?th=1>
 

I installed F35 Workstation on a 256GB USB3 flash drive.  It boots and works, but it is slower than
the Live version.   Why would that be ?

Different USB flash hardware or flash drive about to fail.  SSD's are faster than most USB flash,
but I think some high-end USB flash drives now use SSD technology.  
 

Are there any special settings I should use because the OS is installed on a flash drive ?    Swap ?  I/O ?

I think current kernels have heuristics to choose appropriate settings, but they may guess wrong
for oddball hardware. Some of my spinning disks leave entries in dmesg for failing probes, but
those are expected and handled by the driver.   There are many chipsets for cheap USB devices
that don't adhere to standards, just do the minimum needed to work with Windows.
