Since there are numerous ways to play the chords you just mentioned it is hard to say whether or not you are unneccessarily twisting your fingers into a pretzel or not.

Generally speaking - when talking of fingerings - you need to take a step back and see the whole picture in terms of context. Depending on the chords/notes prior and after the given chord it might in some cases be usefull to go away from the "norm" and fret the chord a bit differently than you would do when you are playing the chord seperately. This has a lot to do with designing your play-flow as economically as possible. Same is true for scale runs and licks. Depending on the context of the song it might make sense playing a certain passage in a way that might look awkward if you rip it out of that context. That of couse is a pretty vast matter and requires some experience and knowledge of the fretboard.

As for personal preference: Yes - what works for you and does not limit you will be fine. Problem is, that without someone more seasoned in that matter monitoring your work, it might lead you to a very uneconomic play. That means you develop quite good in the beginning and sooner or later you are running into a wall and just dont manage to get certain things up to speed or to make them sound good. Getting rid of such "bad habbits" once you got them down and used them for some time (what might be years!) is very hard and sometimes very frustrating. So standing at the beginnig of learning the guitar, you should probably not experiment too much with things like this.

I suggest to go with the "standard" options first and then work you way from there. That should keep you on the safe side.
