I'll give it a try, if Dan or Matt say differently, go with them.
`podman pause` pauses the processes in the container and puts the
container into the "Paused" state. You can kind of think of it as a
flash freeze of the container. The `podman unpause` command unpauses
the container and let's the processes continue running from the point
they were at when they were paused.
`podman stop` is a bigger hammer. It kills all the processes within the
container and puts the container into the "Exited" state. The container
can be restarted with `podman start` and all the processes in the
container will have to restart from scratch.

first, what is the difference between "podman pause" and
"podman
stop", particularly since "man podman-pause" seems to confuse the two:
OPTIONS
--all, -a
Pause all running containers.
EXAMPLE
... snip ...
Pause all running containers.
podman stop -a
^^^^
so anyone reading "man podman-pause" is going to think that "stop"
is
a synonym, at least reading that example.
in addition, "man podman-stop" doesn't help the situation by not
distinguishing between paused and stopped containers:
OPTIONS
--all, -a
Stop all running containers. This does not include paused con‐
tainers.
second issue:
$ podman pause musing_knuth
Error: pause is not supported for rootless containers
$
even if this is true, there is nothing in "man podman-pause" to
suggest that this might occur, which is definitely grounds for
confusion.
