It does take a little time to learn how to coordinate the hand to brain when using a graphics tablet. The way to get rid of this restriction is to get a stylist based PC. I have used a Tablet PC when "doing" photo manipulation since 2005. The Graphics tablet is a learned response, just like when we all first started using a mouse - lo those many decades ago.
On Windows it is easy and simple to opt-out on Wacom's UE settings. I do know that the response of my tablet has improved when using Capture One over the years - maybe I have had an influence after all. (I can hope can't I?) I do find it interesting that some people get all bent out of shape when MS or now Wacom get metadata off of their devices and they continue their preference to use Google, Facebook and Twitter without a second thought.
To answer the question about scaling, you can use almost the entire surface of the tablet - mine has a 1" by 3/4" area around the tablet that the pen "does not see". The Tablet Properties App sets the parameters, you can designate portions of the tablet for the pen to use or use the whole thing. My Graphics Tablet also support touch on my Windows 10 box, I can't say if the same model supplies touch to non-Windows devices. I don't find the touch functions all that convenient, but they are there. Your finger is a terrible thing to use as a brush.
