+1 on that!

The 18i20 would certainly more than cover your current requirements and leave you plenty of scope for
expansion.

You will see from the focusrite blurb at: https://us.focusrite.com/usb-audio-interfaces/scarlett-18i20
it is rack mountable. The front and rear panels cover pretty much all types of impedance inputs you will need (high z, low z using combination XLR and 1/4" Jack sockets with further pad switches to moderate high signals.

If you look at the rear panel in detail you will see that outputs 1 & 2 (highlighted white) are dedicated to line outputs to your powered monitors.

Also shown are other models with less ins and outs if you feel that 18i20 is overkill but these are free standing units.
