Ok, but the question is unanswerable. It’s not known how to convert conventional matter into whatever is strong enough for the Dyson sphere, so it’s not known how much material is available, it’s not known how much coverage it would have, or what diameter it could be built, or what diameter it would be useful.
The explorations I’d seen before assumed using all the non-solar matter in the system to build a sphere with a radius of Earth’s orbit. Ringworld solutions tended to use this diameter as well.
Swarm or other partial modifications (which I don’t know if there’s a term for, but it’s not Dyson sphere) will have other answers, but I don’t think anyone can answer your questions because it’s not currently feasible, and arguably not desirable.
There’s no reason a “kind” superbeing couldn’t build something that leaves Earth nearly unaffected, but it’s unknown how much less efficient it would be than the naive “just use all the inner planets as source material, and to clear out interference”.
Nod, but, this doesn’t answer the actual question.

I agree we can’t get exact numbers here but it’d be surprising to me if modern material science wasn’t capable of generating some upper/lower bounds.
