The crashed Star Destroyer on Jakku shows that there is some power source needed to keep it afloat like in Rogue One
Not necessarily. Ships crash in battle for any number of reasons.
I'm not saying what is better or worse or right or wrong, I'm just saying that based on what we see on screen it seems pretty clear that either a) repulsor-lifts are a passive technology that don't require a massive amount of constant energy or the technology is so robust that failures are rare to the point of being non-existent. No one would live on Cloud City or casually use floating landing platforms if a general power failure meant instant death.
I'm okay with capital ships operating in atmospheres in Star Wars. The Devastator hanging over Jedha in R1 was pretty sweet. Star Trek less so. The Enterprise should keep it's ass--embly in space. But really, repulsor-lifts work based on whatever the script demands at that moment. :cheers
