Choosing a smart home system: KNX, Sterbox, PLC or another?

Hello, I will soon be getting on with the installation in my newly built house (230m2), and now I have a dilemma as to which smart building system to choose. There are quite a few hardware manufacturers on the market. Which system do you recommend KNX, Sterbox, PLC or maybe something else relatively inexpensive. As for the control, I need to control
- lighting / sockets
- roller shutters
- entrance gate / garage door / entrance gate
- garden watering
- alarm / cameras
- heating/cooling
- circulation pump
- etc.
Thank you in advance for your answers

IMHO: Too general an enquiry.
Make the budget more precise,
specify the number of so-called points,
describe what you care most about and what you care less about,
answer if you are an electrical engineer who feels able to do it yourself:
install, ?
run, ?
programming ?
or would you prefer to outsource this to an installation company [to what extent]?

Hello, as for my budget, I think not more than 10 thousand zloty (without cables and box).
What I care most about is the stability of the whole system and global access.
I have already done installations based on KNX, but the components, actuators and actuator controls are expensive, so I am thinking of a PLC or Sterbox.

I am also planning a project of this kind, but I have opted for the IDEC Smart Axis 48sa (I don't remember the full name), but with 30 inputs, including 8 analogue inputs and 18 outputs. so many inputs and outputs and a decent price, and for the time being I am developing a connection and control via tablet, android
