Congratulations man, very exciting to see a fresh build. What are the dimensions of that space? Is it just one room 4k sf? What height are the ceilings?
What is your past experience? If you're thinking about vertical growing I would recommend looking at these threads:

I personally grow with horizontal gavitas but there are many ways to grow good herb.
I would set up 6 foot wide movable (on wheels) farmtek greenhouse benches as long as the room is, cover them in plastic so water can drain towards the gutters. 2 foot aisles in between rows of benches. With 4 foot aisles around the garden. Slightly tilted towards the center with gutters that lead to a bucket with an auto drain pump for runoff.
I like ready gro aeration as a medium with organic liquid nutrients, higher yielding than soil and still get good terpene profiles.
You'll need a climate controlled drying room included in the plan to be most efficient, as well as help trimming most likely. As well as a mother/clone room and a reservoir room. Auto water jackmayoffer style would be great as well.
Some things I have learned in my first year of growing that will save you a ton of time and frustration:
Clean the shit out of the entire space before moving even a single plant in there and keep it clean.
Fully seal the space, don't cut corners on the build
Make sure there are no dead spots in terms of air movement.
Follow the VPD Chart.
The plan is extremely important, things can add up very quickly. Don't forget about proper drainage, drying areas. You need to be able to control all the elements, I highly recommend getting the iponic controller.
Pick the proper strain. I'm not sure where your location is but I'm in a very competitive market and you need to grow not only good quality but the right strains.
Unless you are very experienced I would recommend growing something that yields well and is not too finicky. From proven clone ideally.
For the love of all that is good and holy double trellis. Either leave them there all the time which is optimal or at least put one trellis up beginning of week 1 of flower and beginning of week 4 of flower, especially growing OG's.
If you're able to keep mothers and take very good cuttings that is the best way to avoid getting mites and mold. When getting cuts from other growers I can't overemphasize how important it is to quarantine those cuts until you're sure they're healthy.
Invest in OGBiowar beneficial bacteria. In a side by side comparison the plants that receive biowar teas are much happier.
