I’m not familiar with them myself, I prefer the default UI

Still no one better than Photon.

I see “https://ujournal.com.ua” and i think, i can found any similar, but nothing…

what can you offer besides photon?

I wrote about it about 2 years ago.

https://editorjs.io/

One of its revised versions is used on vc.ru , dtf.ru and tjournal.ru . This helps to improve user interaction with content generation.

I found that now iframes don’t work on lemmy and it’s unclear how to embed videos or playlists. maybe you would consider integrating editorjs? Otherwise, creating comments and posts doesn’t look User friendly.
