You can use omnipotence to never get bored
I choose omnipotence
Yes I think we can
Create object made of neutral charged particles
You didn't take the good way to list superpowers since they are countable.
You should consider the superpowers that someone have as a set. If you consider a nigh omnipotent someone who has infinite powers then you are right in a way because some could have powers that others don't have but you're also wrong since the set of powers of a nigh omnipotent is an infinite countable set it has the same cardinal "aleph zero" (the number of elements) of other infinite countable sets in other words by considering that nigh omnipotent have infinite powers they also have the same number of powers.
Don't mix cardinals which are the numbers of elements of a set and ordinals which are there for ordering set.
Me I like the idea to use the usual classification
It is my opinion but for me great stories are those who can make interesting things which are normally boring. It would be great if you could find interesting powers based on a more scientifically rigourous classification
In physics energy and time are linked properties then if you have a character sufficiently good in physics he can technically manipulate energy by bending time
Fond a full logically way to explain Metapotence and Omnipotence is find a limitation to those powers. We can always find limitation to any explanation of Omnipotence.
An example, can God can lift a rock that he can't lift without proceeding like you explain all the long? Yes he can. God can also decide to erase from existence both your relative and absolute plans and then be able to do anything an everything.
As a generalisation, can God can do anything and everything without proceeding like any explanation a human like us can provide? Being omnipotent yes God can.
Depending of the context
Retrorge, you gave a good explanation but you forget that the empty space between atoms has an utility. When 2 atoms are too close the repulsive electromagnetic force between their electronic cloud ( sorry if we don't say it like that in English ) will be greater than the liaison force between them which will implie your body and the wall to burst
There is also a low chance that you're atoms will fit perfectly with the wall's atoms resulting in complex chemical reactions and the part of your body will be one with the wall but you'll never get back those body's parts
He is omnipotent so He can
Omnipotent can do anything and everything as you said so the can create something they doesn't know.they can know everything but they can decide to don't have any knowledge but be able to create anything and they can also know everything and create something they doesn't know at the same time just like they can be greater than the multiverse an smaller than a single point at the same time.
Omnipotent is not constrained by our logic all what you can imagine they can do it although is very stupid just like create a mountain they cannot lift and then lift it without any difficulty.
Author authority can just be applied on a narrative plan, metapotence doesn't have this limitation
That's my opinion but be absolute undetectable is too dangerous when you live in a society, other cannot detect you then they cannot avoid an accident with you, just cross the road is too dangerous and if you have an accident, a deadly disease or some other things that need to get you an assistance there is no chance for you to survive. Just have a conversation is impossible, nobody can socially interact with you.
Apart if you love loneliness this isn't a good power
They day you'll get lost somewhere without the the possibility to find your way by yourself, I'm sure you'll hate your power
People believe all what I say
Did you try omnilock ?
Technically it's possible to break rocks with fire by using pression an exemple is when there is a great fire in a closed room then by opening the door it creates a giant burst.
Fire give heat then give entropy then give pressure which is an mechanical action
If you can manipulate enough fire to concentrate all the heat in a single point by liberating it you will get enough burst to break rocks, maybe mountain if you can
I can have all over with infinite wishes
