How to properly organize routing in a home network?

Question

network hardware

Good afternoon!
I am planning to reorganize my home network, and I want to make the most transparent distribution of IP addresses between stationary devices, with the most efficient routing.
I previously read articles on Habré (first 3 chapters) linkmeup.ru/blog/11.html and several articles on the Internet, but it only got worse in my mind, so I ask for help from the community.
I have previously compiled the following scheme for myself:
Device Address Connection interface
Router 192.168.0.1 Host
4G modem 192.168.0.2 usb1
Printer 192.168.0.1 usb2
NAS 192.168.1.1 Lan #1
MI BOX 192.168.1.2 Lan #2
Receiver 192.168.1.3 Lan #3
PC 192.168.1.4 Lan #4
Tablet 192.168.2.1 WiFi 2.4 GHz
MI BOX 192.168.2.2 WiFi 5 GHz
Phone [phone] WiFi 5 GHz
Laptop 192.168.2.4 WiFi 2.4 GHz
Guests 192.168.3.x WiFi 2.4&5
GHz And what are the mistakes? It is also planned to add several WiFi signal repeaters with addresses 192.168.0.x
Thank you!
