It's easy to find USB-C to {DisplayPort, Mini DisplayPort, HDMI} adapter cables on Amazon.
I would recommend looking for monitors that have IPS panels and near-100% coverage of sRGB. Vendors of the very cheapest 24" monitors often skimp and use TN panels (that may not have good viewing angles) – or panels that don't offer decent coverage of the "standard" sRGB color gamut. If you don't see these things in the specs, assume the worst.
I only know of a couple of 24" standalone monitors with 4K resolution and Retina-style pixel density. They're from LG, and they cost a lot more than good 24" 1920x1980 pixel monitors. It's not entirely clear why there are so few 24" UHD 4K monitors given how UHD 4K resolution is now so common in TV sets.
