Yeah, I've done this a bunch of times.
You want an injected skin system, preferably with an opaque base. For most applications, a translucent base is going to be more desirable. In this case, however, it's going to reveal a pluggy, 'doll hair' -like pattern, whereas an opaque base will give the appearance of hair growing right out of the scalp with no visible weaving. With a transparent base, you can still go very short, but not quite as short because you can't expose too much of the base (an inch is fine). With a good quality opaque injected thin skin, you can expose the base and only have to leave the hair long enough to conceal the edge along the front and petimeter.
Any other kind of base is going to look like s**t if you try to buzz cut it, honestly. See for example John Travolta's terrible lace full cap with buzz cut in the wrong color.
1" is considerably more forgiving than 1/2". The shorter you go, the more the following info applies:
The template design needs to be damn near perfect, which may be a concern for a first-timer. Perfecting your template is step one.
The other concern is going to be the direction of the hair, especially when there's not enough length to style it effectively. It has to match the growth pattern of your remaining hair quite closely, or the perimiter will show. There are two ways to acheive this: you either indicate it on your template with arrows and hope for the best, or you perm the growth pattern into the wig yourself with a formula for hi-lift/tinted/double processed hair. Otherwise, the generic ventilation out of the box is going to look funny (see again John Travolta).
The nuclear option if you have enough hair left to style it somewhat, is to force it into the direction you want with a heavy, matte product like sumo clay (which i do not recommend).
If you've fabricated a buzz cut out of concealers every day for years, then chances are you know where to place every little crevice in your hairline, every cowlick etc. That would be a huge advantage in designing your template and executing the style. (My advice: keep it natural. If you go for a very stylized, geometric hairline with a system, it's more likely to look fake.)
As noted, the hair will tend to lay very flat unless it's ventilated to stick up and out (which, trust me, you do not want).
You are still going to need a good blend, so that it lays into your hair somewhat, and you'll need to use other tools besides clippers to acheive that, even if it's just a pair of tweezers.
You'll also need to trim your growing hair constantly (like 2x a week) to keep it the same length as the system hair at the join.
Hopefully you're getting the impression that this might not be the easiest, low-maintenance style option. It's certainly possible if you're committed to it.
Also, if you keep it a bit tighter on the back and sides than on top, it will help disguise disparities between your growing hair and the system hair (texture, density, lift etc). If you go 1" on top take the sides down to at least 6/8" or so.
This one is a 'covid-era' stock translucent .08mm injected thin skin base cut down to 5/8" (16mm) with clippers. I use it as a backup currently, on days when I can't be bothered to expose the hairline. It's just resting on my head in the photo, not bonded down:
