A small error - when 2. Qxd7+ the queen cannot move there - the rook is on f6 and in the way. However, if the rook is simply moved to g6 originally there is no problem with this.
1. Rf6 Qxd7 2. Qxd7+ is, in fact, possible! I think you somehow misplaced Rf6 'mentally' on f5 (!?)
Also, your proposed 1. Rg6 does not work due to 1. ... Ka8!, I think. (2. Qg2 Qxg2 3. Rg8+ Qxg8)
1. Rg6 doesn't work either due to 1. ... Kb8, and now 2. Qb3 Qxb3 3. Rg8+ Qxg8.
There is a reason 1. Rf6 is the only correct solution.

Often the composer wants the wrong tries to be tried, I think. At least, I would want to (although I have never composed anything decent).

Nowadays, composers tend go for several thematic tries, without much concern about making them more obvious than the key.
