no help with the first 2 questions.  I use Roon though and can answer question 3.  Roon does offer a digital equalizer of sorts.  I've played with it but don't use it.  I do find roon to be much better than native qobuz for organizing my albums and playing them. I do use that.  Roon can also be used for volume control if you are running directily from your dac to your amp without a pre.

Earthbound,

1) I used the fixed volume output on both the CXN V2 and also on Roon. The cleanest signal streaming music. I adjust volume using me CSP3 preamp.

2) Unless you plan to buy a lot of album downloads (offered w/ Sublime subscription) get the Studio Plan. It's a great deal - same HiRez streaming with both plans.

3) Do some reading up on Roon. It allows you access to a number of streaming services (w/ subscription), music stored on the computer hard drive, and improves the SQ of streamed music. Remember, the CXN V2 is Roon Ready and acts as a Roon endpoint (connects easily to your Roon Core). I have my Core on a desktop with an Intel I7 processor and 16GB of memory + a strong WiFi set up. You'll need a pretty fast computer and WiFi set up, or desktop computer with an Ethernet cable to utilize Roon.

Enjoy!

A dongle question(never thought I’d write those words in my life!), any recommendations for a 5g dongle for the Cambridge cxn v2? I use an iPad and iPhone.
