I recommend a safe room to start with.
You will have a better idea of how kitten proof your house is when he has arrived.
Nothing wrong with leaving kitty alone overnight in a cosy safe room with all things needed (food, water, scratcher, tray, a toy like a jingle ball maybe).
House exploration requires supervision and a clear learned route back to the saferoom for him to run back if he gets overwhelmed.
IMO free house roam for a new little one is too much and will just make him feel lost and alone and maybe scared,
Establish a cosy safe (he feels secure) room for him to mark it all up with his scent and ''own''.
let it be his bedroom until you know he is going to be safe unsupervised (in other rooms)
your boy may be a cable biter ,,, or a bookcase climber (anything) and needs to be kept safe till you know him better.
