I am not a pro and the following my personal opinion only. But...
Comparison with computer keyboard typing is incorrect. For resulting text, the only important are characters hit, second is "words per minute". The rest is completely irrelevant for the result.
In playing keyboard/piano hitting correct keys is important, but that is the basis only. Important is how you hit it, precisely how good you can control the velocity when you hit it (for real acoustic piano there are other aspects). The speed is also just the basis. You need to be able follow and control the tempo, so time intervals between notes.
Especially at the beginning, without correction from a teacher and learning on MIDI keyboard, with high probability you develop incorrect way to play. Your body remember it and that will be a show stopper later. Re-learning is hard.
I understand that the situation, finances and goals can be different. But if you ever plan "play piano", get at least so called "hammer mechanic" MIDI keyboard. Better just Digital Piano. If you have place, normal acoustic upright (old used upright is normally cheaper than used reasonable Digital Piano, disadvantages are space, noise and maintenance). I mean if you will learn on cheap MIDI keyboard with synth mechanic, you will be unable to play on even Digital Piano. The internet is filled with horror videos children learned on MIDI keyboards attempt to play piano... there are no stories with "happy end" there.
Try to effort a teacher. Or at least someone who show you how to position your hands right. Or at least point in case the position you are going to use is unacceptable.
IMHO starting playing piano with scales is not a good idea. Even simple 7 tones C major require smooth hand position movement. Find any book FOR CHILDREN first year piano eduction, there will be many peaces with fixed had position so at least you can theoretically learn to play right (self teaching books for adults usually "jump" too fast, the result is: first notes, small peace, nice simple peace, "I can play piano", game over...)
Scales and the rest of music theory is better to learn separately in parallel, DAWs can be helpful there since you do not have to "play" things in "real time" to understand how different things sounds.
