I haven't, either. Did a little quick browsing at Amazon. It seems Thunderbolt hubs and docks tend to be pricey - from the CalDigit Thunderbolt 4 Element hub or CalDigit TS3+ Thunderbolt 3 dock (maybe $180 or so) up to the higher end Thunderbolt 5 CalDigit dock option at roughly $500, IIRC - so people buying one want it to meet all their port needs, and many have a keyboard/mouse wireless USB-A type receiver and/or some peripherals and don't want to have to bother using an adapter cable.My ideal hub would have a design that matches Apple's aesthetics with a minimum of 4 ports with USB-C connector (ideally 6), 10 Gbps Ethernet, SD Express slot, and CFexpress slot.
But there are USB-C 'port splitter' type hubs, though you won't get Thunderbolt 3, 4 or 5 bandwidth from hub to computer. My point is, I don't think the device you're after exists yet, at least without a number of additional ports (e.g.: USB-A). Just the 10 Gbps ethernet requirement narrows it down a lot (and I imagine restricts you to later generations of TB, not TB3 cheap on the used market).
For fun I did a little digging to see how close I could get. Anker Prime TB5 Docking Station, 14 Ports Thunderbolt 5 Docking Station with 140W Max Charging, 120Gbps Max Transfer, Ambient LED Lighting, Cooling System, Up to 8K Display for Thunderbolt 5/4 Laptops "
- 14-in-1 Thunderbolt 5 Dock: Equipped with a Thunderbolt 5 upstream port, two Thunderbolt 5 downstream ports, two USB-C ports, three USB-A ports, SD and TF card readers, an AC input, a 2.5Gbps Ethernet port, an audio jack, and an HDMI 2.1 or DisplayPort 2.1 port. It also includes an advanced active cooling system for optimal performance even under full load, preventing overheating."
Roughly $400, SD and TF but not CFexpress, the ethernet is 2.5 Gpbs, 4 USB-C ports (2 TB5, 2 USB-C), the aesthetic isn't glaringly dissimilar to Apple's (a matter of taste, granted).
I think what you're after will take 2 hubs/dock + a CFexpress card reader.
Ironically, back in the days of tower and mini-tower computers with empty expansion bays, one could buy port cards and customize like what you want; the computer body itself served the 'dock' function. But that ship hasn't just sailed...it's been burnt to the water.
P.S.: I predict a slow shift toward more USB-C and fewer USB-A ports in docks/hubs with time, but USB-A will persist longterm.
