Mixers and audio interfaces have preamps in most of their channels (just not in their aux/line ins, midi ins, spdif etc). Some mics, like the Shure SM7B, might need a lot of preamping (upwards of 70db) and more than what a typical audio interface or mixer can give, so that might be another thing to be aware of (although condenser mics are generally good in this regard).

About the Yamaha MG10XU, I have one of those I believe, just slightly bigger. I like it a lot as it's cheap, sounds fine and has compressor on the channels to f.ex. keep vocals a little more level. I've actually never hooked mine up to a PC through USB and recorded with it that way because I prefer an audio interface, but it probably works fine.

By the way, note that condenser mics also need phantom power (power through XLR cable). Like for a mixer, just check how many channels have phantom power.

For Shure dynamics, that would be more like the SM58 (vocals), SM57 (guitar cabinets, drums, various) and the SM7B (often considered a good higher end option for podcasting/vocals).
