Ive dabbled in a bit of all of this, and let me say, good luck! Sounds interesting.
Unfortunately, USB is hot garbage imo. The USB-IF, really screwed up USB, especially with all the power negotiation bullshit that has to happen now. Thanks to their ever changing USB3.x super premium plus ultra megaspeed crap that they keep doing, i ended up giving up on a multi-year usb project. Because of their changes, i would have had to change my entire build, and have to mitm usb devices, which i explicitly built my device to avoid. And then theres the USB-C cable, and the stupid process of negotiation and the power cable active crap, just... uhg, i hate usb after going down that rabbit hole.
Yeah I feel that! This is why I stuck with HID and MSC parts of the protocol. And tinyUSB is a little difficult to work with too (though I can't complain, its free and works well!). But yeah I'm glad to be almost done with USB haha.
