I only have a technician license at the moment but wanted to try some longer range stuff so I got an HF radio. I'm extremely new to the hobby so I have little idea what I'm doing lol.

Something like a FT240-43 toroid should work for 80m to 10m.
That is to make a common-mode choke on your feedline. You can always try to improve the RFI emissions from devices in your house by snapping on some ferrite on wall warts etc.
