I don’t think there are any shortcuts. You just have to keep doing it and eventually you will get it. The bottom line is how the chord sounds. You can finger chords a lot of different ways. I don’t use my pinky for the C major. I use my first finger similar to an Am. I have been struggling with guitar for many years. I work full-time, and play a wind instrument in two bands(soon to be one). I would encourage you to learn a little music theory along the way. When you learn a chord, play each note individually and speak them out loud. I got a chord wall chart and bass guitar scales chart too . Also, begin to learn the definitions of a major, minor, major 7th, add9, etc. chords. Scales and modes are very helpful too.
