ESP32 WTH01 - how to plan the connection of modules to the ESP

Hello,
i would like some feedback, I want to connect some modules to my ESP32WTH01 board, the question is where is the best place to connect these modules to make them work together properly?
I have free GPIOs on the board marked in red in the picture. RX and TX are out of the question as I use them for PZEM004T.
All these modules work over I2C, so the question is whether GPIO-4 and GPIO-14 will be ok ? BO this is how I have connected them for the moment.
The MCP23017 module supposedly has both inputs and outputs. I am currently using it for relays- I have connected it to the ESP board and relays to it. Is it possible to connect e.g. ds18b20 as input to this module ?

Of course it is possible, only that in this case you cannot use the ready-made DS18B20 library.

I use ESP Easy in the will to explain. I call the relays connected via the MCP expander with a command e.g. MCPGPIO,1,0.
When I add a new device e.g. DS18B20 in the pin drop-down list there are only GPIOs and no MCPGPIOs - those from the expander, well unless it is to write a rule.

Unfortunately, when it comes to the subject of ESP Easy, it's not my 'field'.

This is how I wired it, this is how it works at the moment - 43% is occupied on the board.

The question is whether I have chosen the right pins, or whether something could possibly be changed.

I understand.
Maybe I need to add a Switch input device MCP23017- I haven't tried that yet

This is a secondary issue for me, but it is also bothering me.

Thank you, that's quite a wide range, but with the limited number of GPIO pins by ethernet taking a few the choice is greatly reduced.
To which pins is it best to connect the YFB6 ? Generic pulse counter ? flow meter (Hall). I connected to GPIO 32 and 17 and it worked.
