USB 3.0 powered hubs that give you more USB 3.0 supporting USB-A ports are pretty easy to find these days.

USB-C ones (that actually give you more than 1 additional USB-C port) are still more challenging, but they do at least exist now (after having been virtually non-existent for years). Caldigit, Plugable, Sabrent, and probably others all have models that will go 1 device port to 3-6 USB-C ports now, and are powered with decent power per-port limits.

I do agree the landscape is far more confusing than it was a decade ago.

Those hubs exist, but my experience is that you can't plug an arbitrary number of devices into them and expect it to work and it's not about power but about how resources in the computer are allocated to ports.
