As far as I’m concerned, you have two options:
1) a mixer such as the Behringer you mention, and an amplifier to go between that and your laptop. You can get one with motorised faders which will be more expensive, or if you are doing a bit of editing, try the Alphatrack (https://www.frontierdesign.com/Products/AlphaTrack) or if you’ve got cash to flash, try the Euphonix systems (https://www.euphonix.com/artist/products/mc_control/).
If you need an all-in-one, try the TASCAM systems, such as the FW1082 (https://www.tascam.com/products/fw-1082.html) which has got your motorized faders etc, AND a mixer, all in one.
