Needing a new Firewall
(alien.top)
UniFi Dream Machine Pro (or SE) or Gateway Pro would be my choice.
In 2019, I decommissioned the UniFi USG's at our office because at the time, they lack many features and switched us to pfSense which has been flawless for the pat 4 years. I recently switched back to UniFi as a firewall and it is night and day difference compared to 2019 and is feature rich now. Multiple WAN IP Support, OpenVPN Support, Wiregard Support, etc.
10G under $200 is going to be tough.
I'd personally build it with a fanless mini PC like this for even less power and zero noise
