What would you consider to be the best seat for a single traveler in the business class cabin? And what are your reasons?

edit to add: other than bulkhead seats - which are not available to book yet. Flights are in December/January

Also for 1 adults + 3 children (ages 7,10 and 12) where would you choose to sit in economy?

That’s what I’m trying to decide for our upcoming flights (husband and kids in economy, I’m in business - that’s just how our family roles 😅 .. ) I’ve chosen the seats already but second guessing my choices!

it’s a 13 hour flight on the LH configuration
