There’s of course other types of lofi you can explore as well. a couple of things you might check out:
Plogue’s chipcrusher offers a nice selection of lofi effects, mostly retro computers, cheap speakers that kind of thing.
You can also record your own impulse responses of lofi gear and apply those with a convolution reverb plugin.
circuit-bent toys can make cool lofi drums and noises, you can make your own or search the web for samples.
playing a sound in a room with a weird hall and recording it with a mic can also work nicely sometimes.
last but not least: you can time-stretch sounds and then squezze them back to normal to get funny results.
