Your upgrade doesn't clear just because there are seats available in F. There have to be seats in F specifically allowed for upgrades - that's the NF part of the equation.
There is a pecking order to upgrades as well; in general, members with status clear before members without status and members with higher status clear before members with lower status.
Apologies if you already know all of this...was unclear after reading your post. As to the original question - if you have no other use for the miles, why not go for it?
