I'm not going to speak much on cycling, tbh I don't think that really matters much in the long run. When it's done it's done, when it gets ugly let it run through no need for knee-jerk reactions or to play mad scientist trying to fix everything. Let things run their course and keep up on your wc's. If you want to give your tank a boost of bac, either find a good tear down with some cycled rock, toss some dry rock in a friends tank that you know is doing well, or pick up some ugly/dying corals on some really nice rocks @ your LFS (all the rock those corals are growing on have been in the water the whole trip over, specifically something that doesn't have the type of coral you want to keep on it to avoid pests), if you have a source NSW, that can't hurt either.
Equipment-wise - stability first, get a controller, a trident or alktron, pick your poison when it comes to how you want to add the big 3 but automate it, run your parameters middle of the road in case your testing is off, have backups of essential equipment in case you have a failure. Things like a Rollermat make life easier but are not essential, and of course an ATO. Outside of that all the basic stuff, skimmer, heaters, etc. If you need carbon / gfo run carbon gfo, same with blocks, pellets, etc.
Lighting whatever is capable of growing SPS. Halide, T5, LED all get the job done; 100% personal preference.
Flow no matter how much you think you need, add more
Livestock, if you really want SPS to thrive focus on it, and focus on fish that are going to be put to work helping your SPS. I'm going mixed reef this time around. Dip everything with Bayer, can QT or isolate and re-dip, your preference. If I am getting things from a truly trusted source I toss it in, with their water YMMV.
Coralline? What do you like cleaning pumps? IDK why people care about coarrline.
Fugues work for some, but I find sooner or late they always fail on me. I had a solid one this go-around was pulling out huge balls of cheato every other week, then poof slowly withered and died putting everything back into the tank. Love the concept who knows maybe I'll give it another go down the road when I finish up this course of KZ products which I believe killed them off.
Water changes, I say do em, automatically, weekly, monthly up to you. If your goal is to build a system that runs without WC then do that, if your goal is long term mature SPS tank, then I walk the path of least complications. Pick a salt stick with it. RO/DI for peace of mind.
Outside of that, doesn't hurt to take a pump and manually blast all your corals now and then even better if you do it before a water change.
Parameters pick a range that you feel is safe even you have an issue with testing and strive to generally be in the middle of it.
TBH I don't see a lot of people succeeding from day one. My current tank is a little over a year old now, and I added sps at around the 1-month mark. I started with a lot of small frags this time (in the past I did a lot of wild & mari) so growth has been slow but now that things are starting to get to either old school frag sizes

or modern mini-colonies I can see things picking up steam, considering I did a tank swap at around the 8-month mark and I'm running a heavily mixed reef this time around I'm quite pleased with the progression. If things stay the course I can see myself having a tank I'm proud of in the next 6 months to a year.
