I have fiber in my house as well; not Google, but got an opportunity and took it. It's a new house and we ran cat 5e everywhere. Maybe some day I'll regret not running cat 6, but I doubt it. I just recently put the ends on the cables, and stopped using wireless for everything. It's made a huge difference, and well worth it. It's not uncommon for 5 people to be streaming something different at the same time, and the wireless just couldn't handle it. Depending, you might be able to replace all of you phone lines with ethernet. You can always use an RJ11 in an RJ45 jack and just decide at the patch panel what it's going to be, phone or ethernet. If this isn't a new house, chances are you have a bunch of unused phone jacks just taking up wall space. And depending, you might just be able to pull the ethernet using the old phone line.
good luck
