My conclusion was the optimal setup was to keep the tank as your main target, use a macro to spam Embrace, and put attacks on macros so that you don't have to change targets (if you have the enemy targeted while spamming Embrace, Eos heals herself).
I actually found an alternate route that I'm pretty happy with. It's a macro that takes advantage of the standard Party List sort (Yourself>Tanks>Heals>DPS) to focus heal the main tank, and I make a separate macro for the OT so I can switch easily:

/echo Embrace Macro Start <se.2><se.2><se.2><se.2>
/pac "Embrace" <2><wait.4>
/pac "Embrace" <2><wait.4>
/pac "Embrace" <2><wait.4>
/pac "Embrace" <2>
/echo Embrace Macro End <se.6><se.6><se.6><se.6>

You can have fewer or more lines depending on what you're comfortable with, but since this is a sustained macro keep in mind that using another macro will cancel it. I added indicators at the beginning and end as a reminder in case it finishes and I want her to continue or I used another macro and need to restart it.

I like this macro a lot because I don't use many other macros outside of Pet abilities (So it's not often that I have to cancel/restart it) and it ensures that no matter who or what I'm targeting, for the next X GCDs she will be healing whoever I designated, regardless of their HP. It's very useful when I'm prepping for a tank buster and I want the tank topped off + shields, or I want to handle AOE heals/shields but need to make sure the tank is getting a steady stream of heals (One place where this shines is P2 of Sephi EX).
