I have non-sandisk microsd cards that work fine --and other sandisk
models of microsd cards that also work. Mostly I use non-ultra sandisk
ones as it turns out.

But once I could boot via USB I no longer use microsd cards very
often in the RPi*'s that can boot from USB without a microsd card
involved.

It does not seem that my direction of activity is
relevant if it is media-type specific for the behavior.
So I'll not be experimenting further with any RPi4B's
(or otherwise).

But if you make a bugzilla report, various things about
your RPi* configurations that you have reported would be
appropriate to include as context.

There are various settings for getting more debug
output on the serial console for the RPi* stages
of things. Some go in the config.txt but one goes
in the eeprom content. As stands it does not seem
that such would have helped for the specific problem:
The problem is later, after the RPi* eeprom and
firmware stages.

You may never need such, but at least you are forwarned
about the possibility if you think it might help
something in the future.
