Audio tips for rewiring old home


We purchased an older home that requires a lot of electrical work before we move in - a new breaker, a new receptacle connecting to the city power, and probably some rewiring bc many of the outlets are not grounded. 
Would appreciate any audio-related tips that I might keep in mind as we do this. I don’t have a lot of extra funds so probably won’t consider a dedicated power line. But I was thinking of adding a few hospital grade outlets in rooms I would likely have a system in, and perhaps try to include data cables so I can plug in rather than use wifi.  Any other ideas? Tnx

For your listening room use shielded cable. I would go 1 gauge heavier than 12.
@ptss what shielded cable would you recommend? Are we talking shielded romex cable? Thanks.
Too funny. When people post, there should be a link to their system page. So people reading their advice can go and look and see if there's any chance the poster has actual experience with what they're talking about. Then you can, you know, sort of get a handle on how likely its good solid info or your run of the mill blather.
