30 gallon tank stocking

Hi! I’m almost done cycling my 30-gallon tank and I’m looking for stocking ideas. I definitely want to keep guppies, and I’m also considering adding cardinal tetras, some snails/shrimp, and maybe a small group of otocinclus.

For a centerpiece fish, I really like the look and personality of the pearl gourami, but would that be too much for the tank? If so, would a group of sparkling gouramis be a better option?

I’d love to hear your suggestions !
