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
