I wanna start off by saying I know that playing more music is the key to most of learning, I am just looking for possible practices to add into that. What I seem to be struggling with is three main things

1. Making the same chord progression sounds totally different.

I've heard many songs that use the same chord progressions, but sound wildly different. I know theres a lot to do with voicing, and what specific instrument you play, vs how it's played. I have a hard time analyzing existing songs in a way to truly figure out what they are doing as my ear training isn't perfect. I can hear the easy stuff such as line cliches and major4 to minor4, but beyond that I get lost.

1. Making fundamental chord progressions sound interesting.

I've heard so many song I love that sound amazing, and I think "oh man, music be something unique" Only to learn it's mainly using 1-4-5. Every time I build with those, I have trouble breaking away from their standard vibe, where are lots of songs seem to do it with ease. They can make "happy" progressions sound dramatic or sad, or neutral ones sound epic.

1. Just overall brain and hand connection

Sometimes I'll be working on a progression, and I'll be able to hear in my head what I want next, but I'll try and try and try, and be unable to find it. I want to build that innate sense, I know it takes lots of time. I want to eventually understand how all chords, and their variants, relate in a key. Every diatonic chord and their major, minor, sus, diminished, augments, 7ths, and the same with non diatonic. Is there any practices to help build this feeling?

Hopefully that all makes sense. I don't take official music classes or anything, just learning as a hobby and passion. Any advice would be appreciated.
