Buying advice for dock to add to new MacBook Pro 2019

[OsbRun]

I have done some research myself and am bewildered by the choice (and prices) so wanted to ask some experts... I have a new MacBook Pro 2019 and want to buy a dock. I want the dock to have the following connections: 1) Ethernet. 2) Thunderbolt-2/HDMI to connect to an Eizo monitor. 3) USB ports for existing HDs. 4) SD card (CF would be useful but son't think these exist). 5) Couple of USB-C. 6) Plus a way of connecting to a 2010 iMac that I'll use as a third monitor. I'd be grateful to hear from anyone who has similar requirements and has been pleased with their purchase. I'm UK-based so any recommendations need to be available here. Many thanks in advance.
