Off topic...help me decorate my new house!!

I’m moving into my new house soon. It an open concept living room, kitchen, and dining room.

My theme is kinda a rustic farmhouse. The walls will be painted a grey and a dark blue.

1. What color couch should I get? No white.

2. I plan to do a shiplap wall. Should it be in the dinning room or living room?

3. Should my barstools match the couch?

Send me some inspiration!
