Sounds like you are doing great.
I play around with inversions and roots in a new song until a combination feels right, comfortable and the transition from one chord to another does not leave my fingers figuratively in a knot. There is no right or wrong, there is what works for you.
If you have the keyboard real estate then it can be useful to walk the chord progressions up and down the keyboard to effect different tones into the song.
Thank you Col, I remember one of the first pieces of advice you gave me was to focus on theory including inversions. Since that post my playing has evolved at a steady pace.
