Looking for stocking advice!

[Jaesthetic]

Which should I add to my 20 gal tank next?

Temp: 75 degrees, pH: 7.2, a HOB filter and a sponge filter

TLDR:
I currently have 3 HG and a bunch of 1-2 week old HG fry in a box.

Tomorrow I will be getting: 2 mystery snails, 7 neocardinia shrimp, and 3 amano shrimp (granted the LFS has them).

Which of the fish that I want to eventually add should I get next:
- CPDs (I definitely want eventually) [8+]

- Pygmy corys [6+] OR otocinclus catfish [6+]

- Chili rasbora [8], Endlers LB [5], OR Rummynose tetras [8]

 

Long version:

Currently I have 3 honey gourami and a bunch of tiny honey gourami fry in the fry box that I will move to a different tank if/when they survive to a little older.

Tomorrow I am going to my LFS and getting 1-2 mystery snails, 7 neocardinia, and possibly a few amano.

I also want to get more fish. In the end for fish I want my HG, the CPDs, and either pygmy corys or otocinclus, but I also want either some chili rasboras, endlers, or rummynose tetras.
I did the calculations on aqadvisor.com and won't be using any combinations of the above numbers that would stock my tank above 85% (mostly around 80%) so stocking level shouldn't be a problem it's more so a concern of what order to add the fish.
 

My entire goal with this tank is centered around a natural, wild theme with celestial pearl danios because they look like tiny trout. I got and planted the plants about a week or two ago, but they have not yet grown out so the tank is still kinda sparse if I were to take out the two large fake plants (I included what it looked like before the plants and fry box).

I will be quarantining any of the new fish for a couple of weeks in a 10 gallon so my plants should have time to fill out in the meantime I think?

 

I've included a picture of my tank just after adding the gouramis and a more recent one after being planted + the fry box.

Can vouch for the CPDs, absolute treat to watch their behavior. Easily spawned within 2 weeks of being in my tank too! After that I would say the corys and otos, as they fill a different role in the tank, whereas the rest would be similar to the CPDs.

I like the tetras idea I think they would look really nice in that tank, Cardinal Tetras to be exact. But CPDs would look great in that setup.

I might go with the CPDs.

Since you have the honey gourami already, you could do the pygmy corys or otos or even some kuhli loaches. 
Personally, I would only do one group out of the others you listed though. I think doing several of those would take away from the appeal of each fish and make the tank too busy overall.

If it was my tank I'd do only the honey gouramis, CPD's, and pygmy corys.  The longer I have fish the more I enjoy fewer kinds of fish with larger numbers in each group, instead of many kinds of fish.
