These guys didn't usually put fancy names to their compositions... it was a lot different back then... So, Beethoven wrote 32 piano sonatas, and all of them are entitled sonata... So we use the name of the key, plus an op. number (opus=work in latin) ... So, when we say Sonata no. 32 op. 111 we all know it is his last sonata and the 111th work he composed in his lifetime (not exactly but more or less)
The choise of key is a rather different matter... Complicated... Practical reasons (like you write a song for a female voice but then a male wants to sing it... so you change the tone/key so that he can sing it but it's still the same piece)... Reasons of taste... mystical/philosofical reasons, striving to be original reasons, writing collections that have a piece in every key (like Bach's 24 Preludes and Fugues that each one is on a different key so that all 12major and 12 minor keys are included once)...
