z-wave wall-powered dimmers and sockets in Ireland?

Hi! I'm moving to a new house and have read through boards, reddit, youtube, ... I find the advice here to be most relevant because it is Ireland specific, so thank you for being such an involved community!
Wanted to get your inputs on dimmers and sockets.

Looking for -
z-wave dimmers and z-wave sockets that are wall-mounted and wall-powered. that are available to deliver to Ireland.

----
lot of details beyond this
----

Rationale -

1 - I want to install a low more power sockets than there exist now, because at my apartment every socket has a extender sitting on it and I wanna move to fewer power extension boxes/cables. for all new sockets I install, i want to go for smart sockets.
2 - for existing sockets, i have >15 wifi switches, so i will reuse them
3 - I live in a small apartment now and have 26 devices connected to my wifi router. i also have very ****ty wifi connection. the baby camera disconnects often, my work laptop disconnects in zoom calls, etc. the new place will also have virgin media, same as old place so i expect bad wifi/internet and don't want to burden it further. the house doesn't have CAT cabling either. even if it did, that doesn't solve the issue much I suppose. I'm planning to install 2-3 Nest points with nest router. because of these reasons I want to discard wifi as the connectivity choice. since I've had so many issues with wifi even in a small apt, i feel like multiplying the wifi devices using wifi based devices won't be a good experience, will be painful.
4 - i read online that zigbee devices often cannot talk to each other because the standard is loosely maintained. so i discarded zigbee.
5 - lutron and lightwave and a few other products use proprietary RF, which my SigO is against from her experiences so rejected those
6 - z-wave I've heard is interoperable very well. it also has the mesh network (like zigbee although). i also already have samsung smart things hub.
7 - my this and previous apartment were smart-ified using wifi switches and/or philips hue (i sold off the hue now). i noticed that sometimes guests and sometimes my wife would use physical switches instead of voice commands for the wifi switches. so i want to combine the physical switches with the virtual switches (voice commands, etc.)
8 - since i don't wanna keep worrying about battery especially for 30+ devices i didn't get buy-in from wife to use battery powered switches
9 - i don't know about neutral connectivity in the house but I'll find out and upgrade if required (how feasible though?)
10 - after hue experience, i feel like smart bulbs are usually not very bright at max power. we want color lights in only 3 of our rooms and in the rest we want to go with dimmable white/warm-white bulbs with a higher max-intensity.

What does that suggest I go with?
- z-wave dimmers
- wall-powered
- wall-mounted
- z-wave sockets
- deliverable to Ireland (reduces options significantly, even more so after brexit, factoring in VAT $$!)

Options I reviewed:
a - lightwaverf - proprietary RF.
b - Lutron - proprietary RF.
c - inovelli - doesn't deliver to Ireland
d - GE z-wave switches - doesn't deliver to Ireland
e - Fibaro - build quality of the switches is not good apparently. gets stuck.
f - sonoff - wifi + seems like it needs the physical switch to remain in on position
g - aurora - zigbee
h - xiaomi - proprietary RF and only works for xiaomi lights

Are there other options I'm missing?
are some of my rationale wrong (I'm guessing the wifi one will draw the most flak)?
are some of these options better than I thought (e.g. do deliver to Ireland)?

Thank you!
