1st large aquarium, Flow and rock placement?

[JWH]

This is my first large saltwater aquarium (previous was a 20 long). Was looking for advice on if my rock placement is good, and what rec's you all have for Flow / power head placement, and placement of corals. This will be a soft and LPS tank. It will hold about 100gal of water plus another 10 in the sump. I have two of the power heads in photo and the one return pump, and will be getting the random current return nozzles. The top of the tape measure will be about the top of the water line, the black circles in the back are about where the return holes are, sharpie in pic for reference. I will be planning on possibly getting another 2 power heads, another return pump, and larger sump in the future; but advice on what I have now would be greatly appreciated. Thank you all in advance, and

stay safe.

I like your rock work configuration. You are off to a fantastic start! I would put a powerhead on each side of the tank facing the middle. One slightly facing to the back of the tank, and the other slightly facing the front. Angle your return to cross the flow giving by your power heads. This will create a nice chaotic water movement in your tank and hopefully eliminate dead spots. That is why it is always a good idea to redirect your power heads from time to time.
Much of your coral placement will depend on your lighting situation. In a softie/lps tank I would go with lower light to increase your polyp extension. Allow those coral to reach for the light, and once your tank is rockin and rollin certain softies will grow like a plague, choking out adjacent coral. Unfortunately there is no telling which coral will take off. This will usually require you to reexamine your aquascape, to make room for your slower growing LPS.

Here is my 116 softie/LPS tank. I use 4 ATI T-5s in a 36"x30"x25" dimension. This wasn't my original plan for the tank. Seems my inhabitants had other plans.
As you can see my LPS are limited to their own island in the sand bed, and the Space Invaders Pectinia is toxic enough to keep softies away. Now the tank is covered by purple/green Rhodactis, Highlighter clove polyps, GSP,and different color palys that now cover the side glass.

I like it!
Just don’t get too close to the left and right glass, if you can get your glass cleaner through, that’s enough.,

I'd leave room on all sides both for access and to help prevent dead spots.

Looks great to me!!

Thank you for the advice, I really appreciate it. I'll be checking back every few days for the next few weeks to see if anyone else has any other words of wisdom for me. I have two clowns in my quarantine tank that have been chilling for a month ready for their new home. Next up will probably be an lawn mower blenny, gotta love Mr. Grumpy face. I'll try and post my diy filter floss holder in the next few days
