I want the Fighters to have magic.1. Your first statement isn't true.
2. If you are willing to ascribe every fantastical effect to 'magic' and then refuse to give fighters any magic, of course there will be problems in giving the fighter fantastical abilities.
3. You could just decide not to do this.
Others want the Fighter to be strictly nonmagic and defacto low tiers.
This thread is about figuring out ways for the Fighter to function and even flourish at the high tiers.
It seems to me, the Fighter must have defacto magic at the highest tiers, in order to flourish. This is the magic of mythic warriors, superheroes, and wuxia. Perhaps it is the magic of a soul expressed thru a physical body, perhaps it is advanced technology, perhaps it is something else, but it is magic by whatever name.
At the same time, the narrative that describes this magic must satisfy 70% or more of all D&D players.
Sometimes supplying magic in ways that minimally antagonize the nonmagic advocates is threading the needle.
I know from 4e, that a failure to supply a satisfactory default narrative can factor into the failure of the game.
The default narrative must be coherent and plausible enough to provide a narrative premise and to allow for the suspension of disbelief.
