I developed my own block, but I don’t recommend as Gutenberg evolves much to fast.
I think ACF Blocks is the best solution. You should be able to create your own block and save it as preset without writing a single line of code. I also plan to replace my blocks with ACF Blocks.
HTH,

Exactly what I searched for but unfortunately neither image_send_to_editor nor img_caption_shortcode seems to work with Gutenberg. Is there any known option to use the ACF fields in media files with Gutenberg (except developing own blocks)?
Cheers,
