Welcome to RC and the hobby!
A 60 gallon is a good size! Is it a reef ready tank?
Fish is honestly your option, but a lot of people also feel tank dimensions are important depending on the fish (such as tangs like to swim so a longer tank is better for them whereas clowns generally find a spot (be an anemone or not) they like and don’t usually travel far so a smaller tank is fine).
Anyway, equipment depends alot on what you want to keep. Lighting, any light will work for a fish only tank but more specialized lighting is needed for corals (this can be cheaper Chinese black boxes such as SmatFarm Viparspectra or Noopsyche to expensive brand name such as Radions, Neptune Sky, etc).
I always recommend a protein skimmer (I run reef octopus and have no other experience with other brands).
Patience is key in this hobby. When you first start, you will have what some people call the “ugly stages” of various algaes. It’s believed, and I feel it’s true, starting with dry rock makes the ugly stages worse than if you start with live rock (generally more expensive and lots of fun (but some possibly bad) hitchhikers to discover.
I know I painted with a broad brush but it all varies on your budget and what you want in the end.
Oh An expense to also consider is powerheads/wavemakers. Some run cheap Jebaos with no issues, others run Vortechs (hundreds of dollars per pump).
