No, there is only one initrd used for cdrom installation. The others are
for netboot, i.e. booting kernel and initrd from a TFTP server. The netboot
initrds don't contain any CD-ROM drivers and won't work for CD-ROM installations.

There is no "netinst" initrd. There are initrds for "cdrom" and "netboot".
NETINST is a normal CD-ROM installation image. It just comes with less
packages than the full CD-ROM sets which provide all packages on the
installation media.
NETINST and netboot are two completely distinct things and not to be
confused.

Correct. The initrd for installed systems is always generated:
# update-initramfs -k $(uname -r) -c -v

I haven't seen any particular slowness issues except for the login delay
with systemd on elgar.
