Yup. seen all of that before.

 So TF == microSD.

and yet they don't work! At least for me.
Has anyone ever booted a Pi (of any sort) using a TF card?

 OP, what cards are you having problems with?  Where did you buy them from?
Any chances they are fakes?
 

Both bought from, and returned to Amazon.
and yes, of course, they could be fakes.

All of these cards do work and store the advertised amount of data.
Using Raspi imager as well as Linux program Disks to write/read/verify 64Gb images and run benchmarks, which do work but show very low read/write speeds. (~9Mb/s).
