This may be totally off base from what you're targeting, but maybe an ESP32 running ESPHome and connected to an E-Ink display such as those sold by Waveshare? https://esphome.io/components/display/waveshare_epaper/ You would probably need some separate system set up to actually generate the content displayed on the screen, depending on what exactly you want to show. It would require a fair amount of work, but would likely be the cheapest and most flexible option.
There's a feature in ESPHome which allows the device to call a URL to download an image at specified intervals, then display it on an attached screen https://esphome.io/components/online_image/#online_image which would require running a service somewhere that generates/renders a new image at regular intervals and makes it available for download via a local URL. For just simple text, I assume there's a simpler way to update what the device shows over the network.
I switched from many separate Proxmox VMs for all my services, to a single VM with like 15 docker compose stacks (though still with separate VMs for things like TrueNAS). So much easier to deal with, though it does have some drawbacks of course
Random failures
If you're a masochist and have a managed switch, you can make do with a device that only has one NIC, by putting WAN and LAN traffic on separate VLANs on the same physical interface...
You can get a free subdomain from https://desec.io/ so maybe that could help? I did that for a while before buying a cheap domain. You'll get something like stuff.dedyn.io

I remember my class went to the school library, and the librarian showed us how to use AskJeeves for the first time. I also remember using Dogpile, wow I haven't thought about that in over 20 years
Whichever you go with, I highly recommend looking into https://github.com/NeptuneHub/AudioMuse-AI, which does analysis on your music so you can generate playlists/mixes from a specific song or from moods/genres
Gonna get two ferrets so I can call myself a small business owner
Too bad it requires either a monthly subscription or a (cost not specified) license purchase
