There is lots of great advice here. Here is a question to ask yourself. Where are you going to be in 3 to 5 years? Smaller is better, IMO for beginners sake, unless this is your dream tank going in a house you own and plan on having it running for 10 + years.
I started my reefing hobby in 2000 with a 38 gal which I had, back then 75 gal was the preferred "starter" size. I was able to have a successful softy/lps in that size. I did have a sump, actually upgraded that within 2 years. I upgraded after 2 years to a 55 with an apartment move, bigger sump, extra halide. I finally bought a house and upgraded to a 65 which I bought off a reefer who was downgrading to a 40 gal. The 65 was more work for me, bigger water changes, etc. I made the decision to downgrade to a 29 gal which fits into a wall space. I have this plumbed to a sandbed and sump. I can do water changes that make a difference in a 5 gallon bucket. I still have to option of adding a larger sump in the basement for more water volume, bigger skimmer, all the extra fancy stuff, but that can lead to more maintenance.
I still grow softies/lps, but may try some easy sps soon.
I also maintain a 120 gal 6 foot tank at a local store which is fish only with rock. It has a foxface, regal tang, couple of damsels, hawkfish and a tomato clown and that seems crowed to me.
Another thing to consider which has been pointed out is biggest tank you can fit, not just the display itself, but the water change buckets, kalk/reactor stuff, rodi unit, ato, salt mixing containers, etc. I practically need a small shed for the support equipment.
