Air conditioning choice

Really dumb questions from a newbie to home automation.
Building a new house and looking now at selecting air conditioners. Will probably have 10+ by the time we are done.
It looks like use Broadlink might be the way to go (???) but:

  1. should I look at any particular air con brands that will make life easier
  2. will I need to put a broadlink (maybe RM Pro) in every room with an Aircon, or can I just set up one at a time, move the Broadlink and then repeat?
  3. is it easier to try to make sure I can attach the Aircon to a smart thermostat (maybe the new Amazon ones or possibly others). Maybe a bit limited on this as we run on 220v here in the Philippines
    Thank you in advance and apologies for being a dummy about this

Looks like 10+ things to go wrong. What’s wrong with one or two central A/C units?

can I just set up one at a time, move the Broadlink and then repeat?

If the IR codes are the same, then yes.

The quotes for central ac here we’re way more expensive
Had one vendor visited today who said it could be 3X the price
