It's a tough subject to lay out an X,Y,then Z plan.... for numerous reasons. Been "finishing" as well as machining wood for over 5 decades and usually don't get into these discussions.
I've come to "accept" Dura-Block co. danding blocks. 3M Gold stick it paper on rolls. Takes a bit of $$ to get set up so for casual use it's probably not on the table? Once things get out of *"shaper work",I usually start with fresh 120 Gold,then 180 to kill that scratch... 220 next to either,start spraying on,or if the type of finish will handle a finer scratch? The 220 is used as the setup for 320... tough to put into words.
The thing about these blocks is they're perfect for reshaping on big stationary sanders(think BIG belt grinders).... so,I'd just take block and grind the radius on any special needs case. A visit to an auto paint joint should have some. Grab a cpl. Here's a screen shot that may be legible?

*Shapers are vertical spindle moulders. An absolute necessity in a wood mill shop. We have a half dz.... they can make repeatability a breeze. They haven't been fully embraced in stock work.... yet. GRC stocks(think that's it)... it's those boys from Europe making stocks these days. Anyway,they came about stocks through their family biz in the furniture/cabinet end of things. Anyway,love their work.... you're seeing some of what shapers can do.
