If anyone is looking for a really good place to get started with SDR, I'd highly recommend the RTL-SDR Blog V3:

Dumb question (and maybe this isn't legal?) but are there SDR transceivers/libraries?

It'd be neat to have a zigbee/zwave hub with my SDR so I could mix and match some stuff.

HackRF One is an option. There are a number of others. Legality varies by country/frequency/power level.

Can also make a Raspberry Pi act as a transmitter (https://github.com/F5OEO/rpitx), which could hit the zwave frequency but not the zigbee one. (Also, make sure to put a low pass filter on it.)

Or even better, a band pass. The output from that pin is really dirty.

I wouldn't recommend it for anything that will actually transmit into an antenna. Even with filters.

Doing zigbee or zwave stuff is a lot easier with zigbee and zwave than with SDR. Just use homeassistant with something like zigbee2mqtt, and you can control your LIDL light with an Ikea light switch and xiaomi movement sensor without any issues.
Yup, lots around. The hint is to look for 'full duplex' SDR.
