It's great that you have realistic goals for yourself, this takes away much frustration and allows you to learn more efficiently.
It does take a little to time get the picking pressure right. Usually, the brain is deciding to either focus on the left hand or the right hand and the other hand gets ignored. But this will all come together with practice.
You definitely have to sacrifice nail length to make it work, at least in the fingering hand. It sounds like you're focusing on all the right things.
Great to have you here, let us know if you have any more questions we can help you with?
best,
