pfsense covers all of the core use-cases for my new and existing networks alike. Firewall, router, traffic classifier, DHCP server IPv4/6, OpenVPN server and client, Wireguard server and client, Certificate Management and Authority, User Manager, DMZ and multi-WAN (incl PPPoE), all with excellent logging incl Syslog to aid traffic analysis and debug. It's very easy to use (which is not true of all firewall software), and it's stunningly robust. Run it on a PC/SBC with multiple NICs or on a dedicated appliance for optimized footprint and power consumption. Support for HA, external packages (OpenVPN Client Export one of the most labour saving of them all), a thriving community and both free and paid support all make for a very predictable experience.
