Public ip Address on customer's device(router or firewall)
How AT&T Wi-Fi Gateway will be configured during the first installation? Is it possible to choose "modem" or "router" mode?
In "modem" mode, will my device(which will be behind AT&T Wi-Fi Gateway) receive public ip address?

No there is no modem mode available on any of the AT&T Gateways.
You can use port mapping to select ports to send your device or select IP/Passthrough mode to have the Public IP shared from the AT&T Gateway and a device on the LAN side of the interface.
It could be a computer, firewall or a third-party router. What device do you have and we can provide the steps to setup IP/Passthrough mode?
Or an alternative depending on what device you have and it's capabilities. However if you get a new BGW320-50x with it's internal ONT your only option is IP/Passthrough at this time.

Here is an article that covers the basics using IP/Passthrough or DMZPlus mode (5268ac only).

My device is pfsense firewall - i would like to setup VPN IPSec Site-2-Site with 2nd location.
It looks that DHCPS-fixed solution is the best option for me.

Yes that's the best option for planning purposes until your install and find out if you get a Gateway & standalone ONT or a BGW320 Gateway/ONT combination.
The BGW320-50x have a 5 Gbps LAN port, what WAN port do you have on your Pfsense box?
If you get a gateway with a standalone ONT then you can look into bypassing the AT&T Gateway using a "Dumb Switch" bypass method. A quick good will give you an overview.
Note: The Dumb Switch Bypass or any bypass method only works in areas where the Infrastructure has not been upgraded to XGS-PON technology then all current know bypass methods don't work.

Pfsense box has 4x1Gb/s ports. The option with bypass method could not work for me. In Dallas area there is a XGS-PON technology as I know.
