If you're up for some light soldering, I'd recommend picking up a few Sonoff Basics and/or wall plugs and then flashing them with ESPHome (https://esphome.io/). These devices are simple and cheap ($5-6 each), basically just an ESP8266 chip connected to a relay, a button, and a status LED. You have to solder to attach four pins to the board so you can flash it, then you can close it up forever. Future updates happen over-the-air.
I am far from being an electrical engineer, and found that these guides, plus a few YouTube videos, got me to the point where this feels routine. I now have over a dozen in my house, controlling all manner of things.
I've also had fun installing temperature and humidity sensors to Wemos D1 Minis ($2-$3, basically just an ESP8266 chip on a development board) to monitor climate around the house. During the winter, houseplants really like to have higher humidity... we bought a bunch of dumb humidifiers at goodwill, installed Sonos Basic relays inside them, and set rules for them to turn on when the humidity in the room drops too low.
