While the USB host chips are a useful method to add USB host to an existing project (I presume you're talking from the SPI devices from, I think, Dallas and possibly FTDI) there are now a bunch of accessible processors with USB host on-board. I think ST do some though I generally find their products hard to get started in. The ones I'd look to for easier out-of-the-box functionality and a smaller (and hence shorter learning curve) are from Raspberry pi. The Pico offers host mode USB but does require, I think, collecting some drivers. There's a tutorial at https://www.youtube.com/watch?v=iOD-NOzgj7o. There's also the very small raspberry pi zeros - A full-on linux environment with integrated USB hosts and all the onboard tools you'd expect from a desktop.
