Once you have a good label printer in the house, you end up labeling things you never thought you'd label. Cables. Boxes. Pantry jars. Power supplies in the server rack. Kids' bento boxes. It's a rabbit hole.
The Brother QL-820NWB is the one to get. It uses thermal paper (no ink, ever), prints 60mm-wide labels at a decent speed, and has WiFi, Ethernet, Bluetooth, and USB — so you can print from your phone, your desktop, your laptop, your homelab dashboard, anywhere. The built-in LCD lets you print labels standalone without a computer, too.
The tapes aren't that cheap, but they last a long time and the peel-and-stick adhesive is durable. Buy the black-on-white 2.4" continuous roll as your daily driver.
