I highly recommend OpenBSD for firewalls, vpn (wireguard), and other edge servers. It has served me well. I love how everything is organized.

The only caveat is limited WiFi support, essentially not 802.11ac or later, so you will need a separate AP.

Most wifi driver firmware is full of remote exploits, and still should never be connected to secure LANs. =3

Yes. I used a Huawei 5G router as cellular backup on my home network OpenBSD router/firewall but I ran Wireguard over it because I trust neither Huawei nor my cellular provider.
