What wall switch should I get

Hello,
I’ve been reading a bunch of topics about wall switch and I’m considering either getting some sonoff if I can flash them without opening them, or some aqara, as I already have the bridge (but they are more expensive!)

However, I don’t know much about electricity and I’m not sure what I should choose regarding the neutral wire that is so often mentioned.

I live in Belgium in an apartment that has been recently renovated.

I opened two switches, this htis what they look like:

2 buttons:

1 button:

Can you tell me if I have a neutral line?
