Pulseaudio was a (slightly) older audio system, pipewire being its
replacement. And there's a pipewire-pulseaudio go-between that can
pretend it's pulseaudio for apps that won't work unless they believe
they're using pulseaudio.
So, you go the old way and at some stage it'll get abandoned, or you go
the new way and find something that they haven't got ready yet.
Your install with allowing erasing would appear to have removed
pulseaudio for the pipewire system, instead (since it complained about
it not being compatible with pulseaudio). Which would be what I'd have
expected you to have in the first place on Fedora 40.
On my Fedora 40 installation I have:
rpm -qa \*pipewire\*|sort
pipewire-1.0.9-1.fc40.x86_64
pipewire-alsa-1.0.9-1.fc40.x86_64
pipewire-gstreamer-1.0.9-1.fc40.x86_64
pipewire-jack-audio-connection-kit-1.0.9-1.fc40.x86_64
pipewire-jack-audio-connection-kit-libs-1.0.9-1.fc40.x86_64
pipewire-libs-1.0.9-1.fc40.x86_64
pipewire-pulseaudio-1.0.9-1.fc40.x86_64
pipewire-utils-1.0.9-1.fc40.x86_64
vlc-plugin-pipewire-3-2.fc40.x86_64
rpm -qa \*pulseaudio\*|sort
pipewire-pulseaudio-1.0.9-1.fc40.x86_64
pulseaudio-libs-16.1-8.fc40.x86_64
pulseaudio-libs-glib2-16.1-8.fc40.x86_64
pulseaudio-utils-16.1-8.fc40.x86_64
vlc-plugin-pulseaudio-3.0.21-15.fc40.x86_64
And if I do a
rpm -ql pipewire-pulseaudio
to see what files it contains, I can see that the pipewire-pulseaudio
service is called:
pipewire-pulse.service
Just to confuse you.
Then, if I do:
systemctl --user status pipewire-pulse pipewire wireplumber
I get:

There's some warnings logged there about unimportant things (I have no
bluetooth hardware on that PC, etc).
This system is using pipewire, with the support for things that expect
to use pulseaudio. And it works reasonably well, though I don't do a
great deal of audio work on it.
My take on the first two services being "disabled" but "active" is that
they aren't something that's running all the time since boot-up, but
are run on-demand.
