Off-topic. I think "Sonar needs" some solution for multichannel Digital Mixers with surface part, but hosts think that "a sampler" is more Sonar related then this question. I personally do not understand that logic...
Back to the topic.
Unfortunately, perfectly working combination of Digital Mixer + Sonar does not exist. Most Mixers are not thought to be used as DAW controllers, I think that post explains what I mean:
https://forums.presonus.com/viewtopic.php?p=15488&sid=a32a310a309820635f109598ac2eb6a7#p15488I have checked documentation for mixers you was mentioning and all of them can not be used as Sonar controllers. So motorized faders, knobs, buttons, etc. can be used to change parameters inside the mixer but not inside Sonar (or any other DAW).
Some other mixers have:
a) special "DAW control" mode, normally limited (f.e. only 8 channels, even if the mixer has more controls)
b) MIDI protocol, usually supposed to control the mixer from something else like iPad app, not in other direction.
Out of the box, Sonar support only Mackie Control protocol. Limiting the number of devices which can be used. No HUI (ProTools), no custom modules for (b).
Third party solutions can be used for (b), f.e. I have plug-in which can work with A&H Q seria. But these mixers do not transfer "fader touch" and send low resolution values, not the best option to control DAW (but in case your primary use for the mixer is live, with recording into Sonar, that is an option).
The only combination for ~$3-4k, which has 8+ good fully functional in Sonar touch sensitive faders and good stable audio input for recording, is Mackie Control (+ extenders for more then 8 channels) as a separate control surface and RME UFX as an audio interface (in fact it is more "rack digital mixer" with steering from computer). Note that such combination will not work without computer and has limited number of channels.
More or less success reports for modern Digital Mixer with limited DAW mode working in Sonar, I have seen Behringer X32 only.
And finally already mentioned A&H Q, if you are ready to scarify advanced functionality in DAW for compactness and the number of channels.
RME UFX in the first proposal can be replaces with modern MOTU interfaces or any Digital Mixer in "an audio interface" mode. The advantage of an audio interface is the possibility to control everything from computer (gain, routing, etc.) while the advantage of Digital Mixer is user friendly stand alone use. Also RME/MOTU can work with low latency, while Digital Mixers will have moderate till big latency for reliable operations.
But... I personally have never seen any digital mixer, RME interface nor Mackie control unit other the on pictures in Internet. But I know HOW any device communicate with Sonar, that is why I have replied
