What kind of garden is it?
It's becoming more and more a Farmers Market farm garden all the time.
25 raised beds roughly 3ft wide and 20ft long. Mostly organic, not certified and never will be, and less tilling every year.
Do you know all the varieties you plan to grow
I like to think so, but there are some pretty persuasive members here on Helpful Gardener. Makes one go Hmm, what about that one. I have about a $450.00 wish list. I probably have to whittle it down some.
or repair a few more customers tools.
what conditions they favor?
I have about 20 years of gardening experience, may not mean anything but I do alright. I buy Territorial Seed, somewhat local and maybe a little acclimatized to my growing conditions. I'm try to build a well balanced soil that will favor any variety of vegetable. Fertilize with fish and kelp, both as a foliar spray and soil drench.
Do you have drip system equipment?
No, not at this time. I did install a 9 zone irrigation system last year. 2 zones are in my vegetable garden and 7 in the orchard. One zone in the garden, is hooked up to overhead sprinklers. Even though I am using water conserving Hunter MP Rotator, IMO a bad idea. They are a good way to spread diseases. Soon the two garden zone will be T-Tape or in-line pressure compensating emitter tubing.
Approx. width of each plant?
Lots of variables here. Monoculture vs Polyculture. Soil fertility etc.
If you are asking about emitter spacing, we like to cover the whole raised bed. A 3ft wide bed could have 3 or 4 lines the length of it. The emitters maybe 12" apart in all directions. Soil structure has a big part in emitter spacing. Water penetrates the soil in a cone shape.

Some of this maybe helpful or blah blah blah.
