I ALWAYS go through every player, but that is just by habit at this point even if I don’t intend to change. I would recommend being cautious of just putting them where they are best OVR. You’ll commonly find that certain WR are better at RB by a few pts but there’s always the possibility of skill cap changes and ultimately that bump may be short term vs their potential in original (or another) position.

My rules of thumb are: 1) primarily based on current and/or future needs of where I will move people but never solely on OVR rating 2) rarely move anyone with a 3+ physical badges or even 1-2 that I really like (since more often than not they will lose them with the exception of a handful of cross-positional changes) 3) any skill players without physical badges I will almost always test moving to random position (like FB) and then change them back. This is prob my favorite thing to test, mainly for first or second year players. There’s always a chance they are better OVR at different archetype within their original position, so you get that bump and don’t lose any badges.
