Open/close blind with a physical switch

Configuration Zigbee
1

I am new to the world of Home Assistant and I want to know your opinion before buying stuff that I don’t need.
My plan is to have 4 blinds that open and close with their own switch and a different switch to control them all. The system should work without the need of internet or WiFi.
I already have Raspberry Pi 4 with home assistant and I need a ZigBee USB dongle, should I be worried about any particular problem for the configuration?

Then I need to install 4 ZigBee curtain actuators and I was thinking about Tuya or Moes (do you suggest one in particular?) that should work fine with Home Assistant.

The problem is now to create a trigger to open all the blind at once. I have a physical wall mounted switch (with the possibility of pushing and keeping pushed the upper and lower button and to release them) not linked with anything (no wires) that need to communicate with Home Assistant, what is the best way to achieve this? Do I need another ZigBee actuator (of course not linked with any motor)? Do I need a smart switch? In this case it is able to detect whether the upper/lower button is pressed and released?
A smart switch like this could be fine?

First things first. When posting a link, anything after and including the ? is unnecessary because it might create tracking cookies and god knows what else.
So, for example, your first link should simply be: https://it.aliexpress.com/item/1005007010573203.html

Secondly, whether the devices you chose are fine to use or not will depend on what Zigbee integration you intend to use. Z2MQTT compatibility can be found here. For the remaining Zigbee integrations (ZHA & Deconz), you can use this to check.

Finally, you can use anything you want to cause all binds to open or close. Just pick any device which is recognised in HA - it can be a remote, a smart switch with an unused gang or one which accepts double clicks, or simply a button/automation set up entirely in software.
All you’d need to do is create a group with all your blinds in that group, then use whatever hardware or software command to trigger the action on that group.

I know that last part is a bit vague, but your possibilities are endless.

Thank you for your help, and I edited the link in post.
As regards the last part my idea was to use a traditional wall mounted switch attached to a smart switch, hopefully it should works fine.
