Which extension for Joomla is suitable?

Question

Joomla

I want to make a database of language courses on the site and allow visitors to choose courses by parameters. I'm trying to find an extension that optimally satisfies the following criteria:
a) minimum buggy,
b) maximum readiness (just add courses),
c) free
In general, in theory this is CCK - Content Construction Kit. At first I wanted to use K2, but it turned out that this functionality is for a fee. There is also jZoo, also paid. I tried Seblod - it seems to be a good thing and free, but development is hard, since there are few materials on it. It seems to me that extensions for online stores should have such ready-made functionality. What can you advise?
