You would need to use the control surface part of that Presonus board/interface as a separate control surface and assign it to Reaper. Not sure what hoops you might or might not need to jump through for that. It will either identify as a MIDI device or a control surface for starters. It's also possible it's not made to use as a separate control surface and this might be tricky (ie need hacking). Sorry, not looking it up right now.
The audio interface part is straightforward. Assign it to Reaper in Preferences/Audio/Device just like any other audio interface.
If you mix live in Reaper... Then you're still preferring and doing that. The digital board wouldn't be used for that in that case. The tricky part might be using that Presonus as a stand alone control surface that you can assign to a DAW app.
To answer the question "What digital boards..." more generally.
A separate audio interface + a separate control surface would be the best choice. A digital board has redundant (when mixing with a DAW) mixing ability you wouldn't want to pay for.
The Behringer/Midas X32 rack might not be a bad choice though. Decent price for just the mic pres and audio interface ability. And then you'd have the built-in digital board you could run with an iPad if you needed a separate stand-alone digital mixer from your DAW.
