Since the Steam Deck has a microSD card reader built-in, having a hub with a card reader isn't terribly important, but by and large it's a feature included on just about every multi-use USB-C hub. The requirements for powering your Steam Deck aren't too bad: you need at least a 45W power supply, so make sure any hub you get supports at least 45W and you're good to go. If you want to use a hub while still charging your Steam Deck you're going to need a hub with Power Delivery 2.0 or Power Delivery 3.0. The Steam Deck itself has only one USB-C port at the top, along with a microSD slot on the bottom, so you can either have it powered or plug in a USB-C peripheral. This, more than any other feature, adds significant cost to the USB hub, so keep that in mind. If you want to connect your Steam Deck to the internet with a wired connection, you'll need a hub with an Ethernet port. Most hubs offer support for the 4K standard, but Steam Deck's native resolution is 1200x800 so there's no need to seek out 4K HDMI support. Of course, if you want to hook your Steam Deck to an external monitor you'll need a hub with HDMI out. The Steam Deck is Bluetooth-enabled, so you can easily pair a Bluetooth mouse or keyboard, but if you would rather be wired, you'll need a hub with at least two USB ports.

It basically comes down to your personal requirements.
