Would depend on length and width of the tank and what the "setup" actually entails. I am assuming since your doing SW your going to do some sort of FOWLR setup...maybe some sort of Trigger (which I would add last) some damsels, bird wrasse, dogface, maroon clown, and your CUC for the bottom. It is hard to say without dimensions, filtration, and setup. For SW I would ask over on one of the reef forums tbh.
I switch to FW exclusively several years ago because it isn't as much of a PITA. I left town for a little over a week and the person watching over my tank made some little mistakes and bleached thousands of dollars of coral and the tank crashed (losing a lot of stock) after several years of running. I know your not wanting to do coral, but I was tired of being taken hostage by SW at that point.
It is a lot of investment (time and mostly $$$)...not hard but $$$ investment to cut down on continual maintenance and time. IME a good diy auto water top off system is a must. I would run RO/DI water line from another room and pump it with a peristaltic pump from your reservoir for your auto water topoff. Although your buying what seems to be a complete setup...I am sure your going to have to sink at least 4-5 times that in it before your tank is running tip top (that is a very conservative estimate).
What would I do? FW with a wet pet and some dithers
