For router hardware look at the PC Engines APU2. Sadly they appear to be out of stock until 2022, but they are great low power devices. I ran OpenWrt on mine in the past and currently running Fedora. Can do about 1Gpbs and cost around $200 built. For managed switches, look at the Aruba Instant-On 1930 series. I've just ordered two of these so I don't have any first hand experience, but the feedback online is generally positive. Do note, these switches can only be managed from HTTPS, but the interface seems clean. From my research the cheaper Tplink and Netgear don't have an isolated management interface, meaning it can be accessed from all vlans. This was a deal breaker for me. I also considered the HP Officeconnect 1820 series switches, but they've been out for a while and I worried their EOL may be coming up shortly. For Access Points, look at the Aruba Instant-On AP 22. The biggest down fall is the access point uses a cloud controller, requiring an internet connection to manage the device. There is no local management. This is the same exact hardware as the Aruba AP-505 which runs for ~$400. Given Aruba makes solid wireless hardware, the advanced features compared to other units in this price range, and the lower price point, I'm willing to give up local management control. After all, I don't modify my AP that often. My Ubiquity access point has crashed multiple times, the most recent crash appeared to be memory leak. Maybe I'm just unlucky, but this aligns to numerous complaints about firmware quality.
