My house is old enough that it doesn’t have neutrals, so I’m kinda limited in what I can install. I’ve been using smart plugs by thirdreality and battery powered buttons. No problems with the smart plugs yet.

That's also what I've been using, they just don't look very permanent or polished in my high traffic areas.
I have been pretty lucky with the Aqara plugs. I have like 8-10 of them at this point and they work really well with homeassistant, giving energy readings and such.
I have installed LEDLUX smart wall socket (around 25€), MOES light switches (around 30€ for a 2-gang switch), both of which are quite easy to install as it replaces what you already have. I have used Sonoff zigbee relays (around 50€ for a pack of 4) as well as Avatto mini zigbee smart switch modules (around 20€, single and 4-gang modules), but it may require some modifications on your current installation
Or go with a zero, plug and play socket, like the Nous A1Z smart socket, around 15€ each. Just plug it onto your wall socket.
Could I trouble you to link a relay you're talking about? Because if it's a naked board that's cool I'll hide it in the wall, but amazon is confused and thinks I mean a switch I think.
