I use a late '13 21.5" at work as a secondary machine/extra display. Those old machines booting off of an external SSD over USB3 are fantastic for basic office work. It ran Monterey just fine once patched with OCLP, and currently runs Ventura just fine as well. While not quite perfect, Universal Control is a great feature to interact with both machines, and AirPlay works well enough when I want to use a more traditional extended desktop.
I'm of the opinion that any machine since Apple started including USB3 should be given a far longer useful life cycle than Apple wants to give them. Had my 2012 non-retina 13" MBP not had liquid damage, it would likely still be my daily driver. I loved that machine.
