There are a couple holes on my home course where I will decide to use a partial wood, or a partial driver from the tee. Also, depending on the lie, I do it from trouble a fair bit too.
The thing that helped me the most is focusing on my sequencing for these shots. I got too used to essentially doing things at X amount of time, rather than step one, step two, etc. So it helps for me to make sure my swing has a "top", where I'm fully set up and ready for a downswing, even with only bringing my hands back 2/3rds of the way that I normally would on a full swing (or whatever percentage I want). This has helped me keep my partial swings relatively close to my full swings in terms of accuracy.
Great ingishts. Jogging my memory here the guy who wrote the book and invented strokes gained proved that long game ecclipses short game when it comes to scoring contrary to popular opinion.
In terms of the putting stats they are a bit out of whack because I tend to forget to tag them.
Distance control is my biggest challenge. I switched to an armlock putter last years because I have tremors in my hands 24/7 so my putting was spraying everywhere . The putting is way better this year. When I can lock in the distance I've been able to drop a few 20 and 35 footers.
I'll definitely consider everything you've mentioned for v3.0.
