Does anyone have any suggestions?
Well, you could get one of the widely available USB-C to multiple USB3-A hubs, then get a bunch of dongles for your new USB-C devices....
I'll get my coat
You're right, it does seem a bit strange that there's no USB-C to more USB-C hub
Not strange really - there's a
huge new market for hubs and docks that bring back "legacy" connectors for customers' existing equipment, but not so many customers with a lot of USB-C peripherals to connect - and producing a USB-C-to-USB-C hub in which the downstream sockets support anything more than USB3.1g1 + the minimum power requirement is a
lot more complex and expensive than a USB3-A hub.
Also, there are
very few USB-C 3.1gen2 peripherals around and, all joking apart, most 3.1g1 peripherals see no real advantage from being connected via USB-C rather than an old fangled USB3-A connector - and non-Apple USB-C peripherals often ship with a USB-A adapter cable.
If you
do have a gen2 device that can actually use the bandwidth - such as a high-end NVMe external SSD - you're probably going to want to connect it directly to the host for maximum performance, not via a hub. Ditto displays: you don't really
want to connect a display via a USB-C hub, since a 4k@60Hz display causes every other device on that host socket to fall back to USB 2 speeds - so
that's best connected directly to the host, too. As for power delivery, a USB3-A socket can run a 2.5" hard drive or charge a phone just fine - the main
peripherals that benefit from USB-C are the hubs themselves, that need to power
several such devices.
Sorry, but apart from replacing MicroUSB on mobile devices, USB-C is classic case of "a solution looking for a problem".
