You answered your own question, so fine there.
Just a caution on the Bolivian pair. I don't normally recommend a cichlid with gourami, but here we have room and the species being considered for both are probably the most docile. The Bolivian is good as a single fish. It mentions in the profile that in its habitat it has been observed to live in solitude.
A bonded pair is fine, if you can get one. First difficulty is that this fish is difficult to distinguish male/female at the young age one often sees it in stores. Sometimes carefully observing its behaviour will clue one in. And here we come to the "bonded" aspect. Males select the female they will pair with; when this happens, we call it a bonded pair. They tend to remain bonded for life. If a male/female are placed in a tank and the male does not bond with the female, he will usually hound her to the point where she dies. I've had this occur in my heavily-planted 5-foot 115g tank, where one might have expected the female to find sufficient shelter.
Another aspect of cichlids is that with a pair, they will spawn, repeatedly. And they are devoted parents in protecting eggs and fry. Other fish in the tank, depending what they are, can be targeted. Catfish are particularly vulnderable to this, since by nature they just amble along poking their noses everywhere.
Research well, so you are prepared.
