Ubiquiti gear for me. I actually just swapped a in a 48 port PoE switch for the 24 I was running before. Also the UDM Pro, and WiFi 6 access points. Have a few smaller PoE powered switches, like in the entertainment center.
For some small tasks I have a rack mounted thing for holding raspberry pis, so have two dedicated pis for Pi-hole instances that also provide addresses for my .internal addressing. One pi for Home Assistant and one for homebridge. Big media server for running Plex, Channels DVR, Sonarr, Radarr, Jackett, Deluge, my local CA, nginx reverse proxy for everything, Nextcloud, etc.
The Pi-holes point to Cloudflare's newer filtered DNS offering and then apply their own blocklists. Mostly have two so I can take one down for maintenance without the network losing DNS resolution.
I'm lucky and have AT&T fiber to the house which is a nice 1Gb/1Gb for 70USD/month. Using the wpa_supplicant method to bypass their hardware.
