Help stocking a 36g bowfront

[Marshmallowing]

Hi everyone,
So I have a 36 gallon bowfront tank I'd like to make into a big community. I have a few fish in there now, but I'd like to have some more and a bigger centerpiece fish.

Right now there's 5 fish in there:
3 platys, 1 male 2 females
1 sparkling gourami
1 striped raphael catfish (1 and a half inches long)

I ordered in some bleeding heart tetras from my lps store and I'm going to go pick them up later this week hopefully. So I'll have either 4 or 5 of those in the tank by then, too.

The water has a pH of 7.0, the temperature is a constant 78 degrees and the tank will get 50-70% or more water changes weekly. The tank is bare bottom right now but once I get my pool filter sand in it'll have sand substrate.

Any other stocking ideas or recommendations? I like active, personality filled and fun to watch fish. No aggressive fish, please. No livebearers either. I might get two more platys but that'd be it. I've had mollies and swordtails before so I want some fish I've never had before.
I want to get some corydora catfish, but I've had bad luck with them before so I'm not really sure.. I might try again, though.

For the centerpiece fish, I'd like to have a bigger fish but nothing huge. I might get a dwarf gourami but I want something unique. Please don't recommend an angelfish either.
Any help will be greatly appreciated, thanks!

If you want active skip the Raphael cat. I had a striped one and they are nocturnal. You see them once in a blue moon and that's with the lights off..

I'm well aware of that ^^'
My raphael has been plenty active at night for the time I've had him. In fact, I can see him right now. He'll most likely become more of a recluse as he gets older, but that's in their nature and is perfectly fine by me.
