Hi. The return really depends on the size of the drainand or emergency drain you'll be using.
In general if a pump output is rated 190gph, that was measured with zero head pressure. Meaning water pumped horizontal along a line of hose. Which is never the case in hoke aquariums (some exceptions) so if your pumping say 4 feet up to the display tank you will be getting more like 140 to 150 gph.
What I would always suggest is running the return through a manifold. (plumbing with multiple valves). it sounds like you may not have room for that so what I would do is use that pump and add valve in line of the return line so your can control the flow. That way you can tune it to get the maximum flow workout causing any drain issues.
If you have a DC powered pump then you will have the controller to do this for you.
Overall the 190g pulp will be fine. It's always advised to go bigger on the return so you can use it to run other equipment you might add later to.

This is a diy manifold. They can be as large or small as you like and make maintenance alot cleaner and easier as well as give you more accurate control of flow rates.

I do have a controller on the pump to reduce the flow

I’ve got a 20 gallon long with a 10 gallon sump. Return pump is a sicce syncra silent. It’s rated at 251gph and works how I would expect it! I have some strong flow, but it comes from my wave maker not the return.

Then you'll be fine with that pump. As for the actual Gph that pass through the system you'll only know if you use a flow meter. But that's not to important. As long as you get good circulation and a quiet drain your all good.
