well here is what i would do i have only been in hobby a year and i have made some changes etc,
since u have the 1 tank to work with u already have a nice sand bed and a nice amount of lr start out with a community, do not get a SS starfish or horseshoe crab or diamond goby, they will kill your sb in no time this leaves u the option of a nice mandrian later on, i would say no angels for right now which should not be added for 6 months anyway, start out with reef safe fish only just a few then in a month or 2 add some mushrooms or a colt coral once u do that u will start to see what it could like if u like the corals then u are in good shape because u already only have reef safe fish add more corals and a tang or 2 school of cardinals or green chromies, if u don't like the corals then u are open to angels etc, u have a dsb already so u will have some sort of counch snails etc, to keep everything nice and clean so i would rule out aggressive if it were me I want to enjoy my time looking at my tank more than cleaning it and worrying about sloppy eaters, but keep in mind reef tank is not a piece of cake u must watch u water par at every level and does require more buffering , i have a 75 and i am getting ridding of my trouble makers now so i can convert to reef only, but i am fortiunte enough that i am also getting my 200 in a week so i can have my angels , touch decision but sit down get cracking and give it lots of thought
