Matija! Just in case you don't already know, there's an effort underway called the Full Site Editing Outreach Program that might be of interest for you to join as you start exploring FSE this year:

https://make.wordpress.org/test/handbook/full-site-editing-outreach-experiment/

It would be awesome to have you there to help get feedback directly to those working on these features! You can find the group in WordPress.org slack under #fse-outreach-experiment. If you have any questions, feel free to message me directly (@annezazu).
