Some (Possibly Stupid) Question About Scales On A Keyboard

[VexedToRestOnYou]

Ok so I know it is good to practice scales and all on a keyboard with proper fingering. However, does that same fingering apply when you are soling or improvising? So for example if I was soloing in the key of C the following pattern (note the pattern is random I chose it for the purpose of inquiry):

A B C G F E F D (All in the same octave)

Would I use the following fingering:

3 4 1 5 4 3 4 2

?

Here is another example (the beginning of the riff in the song Fancy Footwork by Chromeo after the main vocals in the chorus):

Eb F Ab Bb C Bb Ab C Bb Ab

Would this be the fingering:

3 1 3 4 5 4 3 5 4 3

?

Basically what I am asking is are you supposed to stick to the standard scale fingering when riffing and soloing or are their certain ways you are supposed to "break away" from the standard fingering. Also, I know for guitar, there are patterns you practice like 1-4-3-2. Is there anything like that for keyboard, like exercises that go through the scales but in a pattern for exercises (I think its called phrasing)? If there is, do you still maintain the scale's fingering or are there other fingerings?

Depends on what you played before it. A scale starting on a white key always starts with the thumb. (Black key then index finger, I think.) But if played a note before it, it might dictate another finger. You could even start your scale/solo with a different finger regardless, but 3 feels weird to me. I can imagine 2, not 3, at least not going into a scale.
