2.4Ghz is pretty much only used by IoT, you generally don't care about channel width there. When your client device (laptop, phone) downgrades to 2.4Ghz it might as well disconnect because it's unusable.
5Ghz get stopped by a drywall, so unless your walls are just right to bounce off single, you need AP in every room. Ceiling mounting is pretty much required and you're pretty much free to use channels as wide as your device support and local laws allow.
6Ghz get stopped by a piece of paper, so the same as 5Ghz except you won't get 6Ghz unless you have haev direct line of sight to the AP.
