This Sony MRW-S3 looks like a great hub, and has the benefit of being from a company which isn't some small 3rd tier Chinese manufacturer that just sells on Amazon or whatever.

I hope this works with both the 2019/2020 iPad Pros and with my 2017 MacBook. (I only need USB 3.1 Gen 1 speeds.) Unfortunately, my guess is this will be insanely expensive.

Sony Electronics Launches World’s Fastest Smart Multifunction USB Hub with UHS-II SD/microSD Reader for Efficient Workflow
Sony Electronics - 07/12/2019
SAN DIEGO — July 12, 2019 — Sony Electronics today continues to make ultra-high-speed, reliable and efficient workflow a reality for professionals, with the introduction of the MRW-S3 – the world’s fastest UHS-II SD/microSD card reader and USB Hub with USB 3.1 Gen 2 and up to 100W USB Power Delivery (USB PD) and HDMI output capability support.
Sony has also introduced an addition to its TOUGH SD card range with the launch of the TOUGH SF-M series.
Power through projects
Professional photographers, videographers and creators no longer need to worry about carrying numerous adapters or fret about using up ports on their latest PCs with USB Type-C TM ports. The MRW-S3 is a one-stop solution for fast and reliable data transfer in the form of a handy USB Hub.
The world’s fastest UHS-II SD and microSD card reader handles everything from high-resolution RAW image files to 4K videos and allows the user to maximize their creativity affording more time to spend on retouching and editing content.
The MRW-S3 is also the fastest USB Hub supporting USB 3.1 Gen 2 which provides ultra-high-speed data transfer of up to 1000MB/s2. This brings out the full speed of each USB device so that professionals can make the most of their high-speed External SSDs like Sony’s SL-M and SL-C TOUGH specification series.
In addition, the MRW-S3 can receive up to 100W USB Power Delivery (USB PD)3 to ensure stable and reliable connections with USB devices. Users can be notified by the USB power level indicators if each port is ready to be connected at max power supply levels, eliminating worries of sudden disconnection due to poor power management.
Simplify your work life
The MRW-S3 has a HDMI output with 4K 30fps capabilities, to connect to external monitors without the hassle of carrying extra adaptors or sacrificing limited ports on your PC4.
The powerful USB Hub has a durable aluminum body with a wave surface to prevent scratches, while the grip makes handling easier than ever, especially when connecting and disconnecting devices. The MRW-S3 weighs a mere 95g and comes with a detachable USB-C to USB-C cable for connecting to the host PC and helps prevent cable damage. This cable also can be used for connecting to USB 3.1 Gen 2 devices or to a USB PD AC adapter up to 100W, thanks to its embedded eMarker.
