With all of my wedges/short irons I have 4 main shot types that I use to hit the ball different distances with different trajectories.
I have my "normal" shot with standard yardage and ball flight, a "knockdown" shot with shorter yardage and lower ball flight, a "3/4" shot with shorter yardage and normal ball flight, and a "1/2" shot with shorter-still yardage and normal trajectory. Of those shots, the only one with a swing that is intentionally different in any way is the "knockdown" shot where I move the ball back a little and keep a bit more shaft lean at impact.
Multiple sets of irons and wedges ago I used a shag bag and a big field to measure out how far I hit each of those 4 shots on average with all my clubs 8i and below, then I printed out some homemade shaft labels and put them on the corresponding club for easy reference. Nowadays I don't do that (they get damaged and fall off too quickly/easily without real shaft labels), but I do have those distances noted on a laminated sheet I keep in my yardage book cover. I rarely carry an actual yardage book, it's mostly just to keep my scorecard dry and intact now that I live in a more humid climate where sweat doesn't immediately evaporate, but it means I can have a typed out sheet of these yardages handy at all times without taping them to my shafts.
So long as there isn't some forced carry or super slippery greens conditions that would necessitate a shot with more spin or higher trajectory I've found this to be much more consistent than just using a 60* for everything inside its full swing yardage and trying to tell the small difference between a 70% swing and an 80% swing.
If you have a decently equipped shop or set of tools you may have all you need. A golf wrench is just a T25 torx bit on a torque-wrench set to 40 in.lbs. 😁
