You can basically 'retcon' the way things are to any set of plausible alternatives, as long as it'd be possible, you can set something to a different state, however, this depends on how simple it'd be to convince people that what you change simply is that way.

For instance, you can make an old building luxuriously furnished inside, since very few people would have even acknowledged it before, you may also change the paint job. Basically, that feeling you get when you see a new fast food place in a location you didn't even knew had a building crew, but you just shrug it off? Yeah, if you can't get that effect on people, the change won't take place, so anything well known is off limits (like the Eiffel Tower's height), and so is anything that no one would accept as possible, hence the limitations at the beginning.

At face value, the power grants you a form of teleportation where you disconnect from your current location and reconnect to a different spot in the universe. You may permanently bridge two points in space to create surfaces you can no-clip through to get to the other side. But then, you realize the power doesn't just let you relocate matter, but the properties of objects, and even concepts too, for instance, you can dissociate your senses, so you could be watching the sunset in another continent while it's early morning where you live. You could separate your physical composition from your visual appearance, so your mass and solidness becomes invisible while the image that appears to be you (but it's just a part of your whole) is intangible and weightless, something like separating a model from its hitbox. Both the image and the mass would be synchronized tho, it's not duplication, so you could be physcally sitting in a chair while your image floats in the air, apparently sitting on nothing.
You could place your voice right next to someone's ear, or project a megaphone's in the middle of a crowd. Make a spring powered blade swing appear in front of something for an unexpected cut, remove the kinetic energy and momentum from an object, displace the light input of a camera to make undetectable hidden cameras... etc

Mild telekinesis restricted to what you could do with your limbs comes included, without the full body having to stay together, like petting a cat in your backyard while you punch a rober in your porch, with as much strength as you actually have. The upside is that you can relocate anything that is in direct contact with your body or something/someone that your body is in contact with, for instance, a marble a kid swallowed just by touching the kid's head, there isn't a mass limit, but you can't relocate anything that constitutes a "place", as arbitray as that seems, this is the weakest part of the concept, I'd like to see where it goes.

TL;DR, What powers could mess you up from over-reliance or the way they'd change your life?

In my case Lifelike Simulations, I may one day not know what's real and what's not.

Unabridged:

Especially on the psychological level, I don't mean the temptation to 'become corrupted' and do evil stuff, like if you had mind control. I'd like to know what powers you've considered could mess you up, and how?

In my case, perfect daydreamed simulation, somewhat of a mix of lucid dreaming and future sight, allowing for full experimentation of any scenario, without the realistic boundaries And the burden of actually having committed an action from Time Rewinding.

It'd be nice to asses any decision before making it, knowing how to approach someone, and even live out fantasies without making any of it be real.

But, I'm afraid I could eventually be unsure if what I'm living is real, imagine if you made a joke, flirted with a stranger, or committed a crime thinking you are in a simulation because you've grown too used to it, there'd be no do-overs, and while you could simulate scenarios until you get a list of actions to get out of trouble, the guilt and shame would be very real.

Would this potentially be a problem to you?

What set of powers might be?

I'm in a vulnerable state, again, so I'd like to watch/read a fantasy story where there's a well developed romance, preferably monogamous, but I'l accept other options out of curiosity.

I'd like for some sort of steady progress to be seen, the love interest doesn't have to be on every part of the story, but the protagonist should have at least the intention to get with them eventually.

Non Isekai fantasy is more than welcomed, but you can gess relatability plays a role here.

In synthesis, stories where a romance is clearly brewing, and it isn't just a sort of ship made by the author to which they may never comit; nor it's on the other end of the spectrum where the relationship falls out of the sky or is Literally Bought.
