I'm only a week in as a re-beginner. My question is about fingering and I'll use E minor as an example.

Most resources state to play with fingers 2-3 although in the intro lessons this is taught with fingers 1-2 (which I realize is an alternate). This method makes switching between Am and Em fairly easy and sure enough, the first 2-chord switching exercise song features this switch as a pivot.

However, I can't help but feel given the other major shapes like C, D and E, leaving my index finger "free" will pay dividends down the line.

Would like your thoughts on this. Do you recommend staying with the chords as taught or simply spending more time now switching between the non-pivot versions for the exercise knowing that approach is harder but will pay dividends down the line. Same is true of "pinky G".

Thanks!
