I got myself one of these things: https://www.rapoo-eu.com/product/8000m/
It's a compact combo wireless mouse and keyboard set. I needed a cheap wifi keyboard without the numpad for work, but this ended up being awesome in so many ways... It connects over wifi via its standard USB dongle, and while I knew it also had Bluetooth connectivity, I hadn't realized it had nothing to do with the dongle - both devices are separate BT accessories. What's more, the keyboard switches between wifi and three separate paired BT devices at the click of a button, so I've gotten used to keeping my phone close and when I get a message, I just click over to Bluetooth and answer, and click back without picking up the phone which is just bonkers to me. Also, batteries last forever and each device only takes a single AA battery...
