Another approach is to look not for things advertised as "monitors" but instead look for "digital signage"[1]. Nowadays most of these contain some networking features but they'll be oriented at local control (i.e. by you via something on your LAN), not some third-party control center accessed via the internet.
Anecdotally this is the approach I took ~20 years ago when buying a (then slightly exotic) plasma flatscreen from Panasonic. It is still working flawlessly today, though I keep hoping it will die so I can guiltlessly replace it with something newer/bigger/higher-resolution.
