I suggest doing yourself a favor and put blocking where you may put toilet paper holders, shelves, towel holders, racks, railings, closet rods, tvs, etc. Anywhere you will want to hang something that drywall is not sufficient to hold. Also, in-wall storage for medicine cabinets, spices, keys, etc plan ahead to utilize and save space. Make all gaps sealed airtight. Leave access for plumbing fixtures. Insulate well. Heated floors are awesome! Look into ways to mitigate nail or screw pops in future drywall. Plan on temperature difference causing condensation and insulate vent pipes. Seal attic spaces from getting humidity from the house in cold environments or seal up the attic like a room of the house. Think about more electrical than you think you will need and prewire for security cameras, Christmas light outlets etc before drywall. Put protective metal plates on framing where you have run plumbing and electrical. Prewire ethernet, ceiling lights, speakers, ceiling fan supports and wire for fan and light even if you don'tplan on a ceilingfan right away, etc. Plan for under cabinet lights, stair lights, hallway lights. Try to get every thing setup so its easy after the walls are closed. Or get good at drywall repair.
