Hello and welcome!
You have found the right place here for friendly, and informative advice.
Lovely big tank you have there! I can't really tell, but is that real plants you have in there of fake? If real, then this is a really good start!
I agree with what others have said, and until you know the parameters of your water there is not really a lot we, or yourself can do regarding stocking suggestions.
As far as the cycle is concerned though, I must say that my experience of fish 'in' cycling wasn't painful at all, and I still have my fish that were used. I apparently bypassed the cycle process by adding LOTS of real plants, stuff like Green Cabomba
etc around 10 plants in a 29g (just to give you an idea) I also used a product called API quick start, which is a bacterial supplement that is supposed to feed your filter with bacteria to kick start the cycle process. (there are many different opinions on these products) but it seemed to work for me, as I never really noticed a noticeable cycle so to speak. I did have a slight spike in nitrite in the second week, but a couple of partial water changes sorted that out. Never had a problem since.
I must say, I chose unwisely though to begin with and now am stuck with fish that I like....but would prefer something different. I chose fish that I wouldn't kill, and would be easy to look after. This first step is definitely a very important one, and does require some consideration. I used Glow light tetra, to start with, then a group of Danios as the next lot of fish in, and I would much rather have more interesting fish, but they must have helped with the cycle, and the more exotic fish will just not tolerate the fluctuations in water parameters during the cycle, so its a catch 22 situation...
If that was my tank..... I would have it heavily planted with real plants, and a couple of large groups of some nice schooling fish 10-15 of each species maybe, maybe a nice centre piece fish (this would depend on water params) and maybe half dozen corys on the substrate. and/or some kind of loaches.
What species of these fish, that all depends on you, and your type of water.
Good luck, and keep us posted on the progress!
