As Duncan suggested you could follow the handbook, and it will work,
but the sequencing is suboptimal.

Merging systemd install instructions into the handbook is something on
my to-do list.

Looking at my notes the last time I looked at the details you just
need to pick a systemd profile at the point where you pick a profile.
Then you need to do these steps before you emerge -u world (the steps
are in the handbook, but not necessarily in the right order):
1. Edit locale.gen and run locale-gen
2. Pick your profile with eselect profile
3. Run ln -sf /proc/self/mounts /etc/mtab   (why this isn't already in
baselayout is beyond me)
4. echo "EST5EDT" > /etc/timezone

Then when you emerge -u world these settings will get migrated to
systemd automatically.

When you're done you just add
GRUB_CMDLINE_LINUX="init=/usr/lib/systemd/systemd" to your
/etc/default/grub before running grub2-mkconfig.

If you're having booting issues it probably has nothing to do with
systemd itself - that seems like a bootloader/initramfs problem.  I'd
recommend using dracut and grub2 as they tend to be much smarter about
such things.

To get your network running you'll need to enable/start
systemd-networkd or the network manager of your choice.  If you don't
want to use networkd then make sure you install your choice of
networkd before you reboot while you still have a network, or just use
networkd until you get another network manager installed/configured.
If you're just using dhcp it doesn't require any configuration.

You did mention "without openrc" - while being able to install without
openrc is on the to-do list right now there are still a few packages
which use openrc instead of sys-apps/gentoo-functions and until these
are fixed we have openrc in the system set so that it is hard to
remove.  Once these are fixed then I suspect we'll get to a point
where picking/installing your service manager/init are just like
picking your bootloader and kernel.

You're welcome to follow my notes, but they also include the use of
btrfs which you may or may not want to use:
