The buttons are cheap and use the EV1527 code. They're available in at least white housings with red, yellow, green or blue ring. ZigBee versions in similar looking cases are also available (one version is a sos button), but I haven't bought one because it's not that cheap. Let me know if it also fits there, when you find out. I've only tested the 433 MHz version, but I guess 315 MHz is the same.
The blank file can be modified in the slicer to add custom text, about 0.4 mm depth is good.
Also you can use the OpenSCAD file and modify line 15. It's quick and dirty, but works.
It's also possible to use svgs like https://pictogrammers.com/library/mdi/ that I've used for the 433_mdi_* files.
I'd recommend a fancy print plate for a nice finish, but the choice is yours.
The 315/433 MHz receiver of the relais switch module can easily be modified to become an universal ESPHome remote receiver, so the buttons can be used with HomeAssistant.
