Nightly rsync to two NAS boxes in the house (TrueNAS Scale and a Synology). Docs go in NextCloud, hosted on a VM in my basement, which is also backed up to the Synology by Proxmox. Also backing up my main machine (Pop!_OS) and my wife’s laptop (ThinkPad E595, also Pop!_OS) using Spideroak One.
Look into commercial monitors like the Samsung BET-H series. I bought a 43” one years ago, plugged an Apple TV into it, and haven’t really thought about the screen ever since.
According to the specs it runs Tizen, but I haven’t had to look at a menu since I got the settings dialed in, i.e. years, so I completely forgot. Don’t even know where the OEM remote is, it works with the HDMI-CEC commands sent by the Apple TV.
