med-high flow, low light(partial shade) coral suggestion

[BangingBaking]

Long story short, I lost all livestock in July while combating a bubble algae outbreak with peroxide. Though I didn't spot any symptoms of disease, I let my tank fallow for 4 months, and now I'm back on track with a QT tank and a new fish added.
During the fallow period, I ghost-fed pellets every 3days to prevent my nutrients from bottoming out, and my corals were all fine. I also re-spaced my tanks so that each rock section will be modular, allowing me to manually remove any piece I want without destroying the layout and scrub nuisance algae in case of an outbreak (decided to battle future algae issue with manual removal since this tank is so small, it's not too bad).



I'm regaining my motivation and want to add new corals, but I need suggestions for compatibility. The area I want to place them is the midsection of the tank, where the back half is shaded by the magnetic island. It also get rather direct flow from the power head I placed in the center bottom back of my tank to prevent detritus buildup within the rock work

Was thinking of placing a Button Scoly vertically on the front side, but would that be a good idea? Or are there other corals that are recommended?
I guess my tank is lacking purple/blue, any suggestion will be appreciated!
thx in advance.

The back wall is going to be tough because it looks like there is almost no light reaching that area.
As to the scoly, I'm not a keeper of them but I have never seen one attached vertically. Most all I see are on the sand bed with a rare one placed on rock. I'm not sure any fleshy LPS would be a good candidate to glue to the back wall but my experience is limited so maybe someone else can help out more.
