I agree with this. Scales more or less have an accepted fingering so if you practice these a lot, you'll gain some natural muscle intuition for when you see variations on scales and arpeggios in the wild. When I took classical piano lessons, each week we'd have a new key assignment and we'd have to practice scales, chords, and arpeggios in that key. My piano teacher hand crafted a very nice sheet that listed all scale and arpeggio fingering for all keys, but that is buried somewhere in storage. This website [1] seems to have the same info.
