Answer 1

You're right - PHP serialization looks very similar. Either do JSON.
I dont thinks is standard format. Where is it come from?

BTW, here are common serialization formats https://en.wikipedia.org/wiki/Comparison_of_data_serialization_formats

Comparision of example arrays below in article

Answer 2

Did You managed db migration already? I can advice You to use plugin that can handle this for You, for example WP Migrate DB - it handle serialized data pretty well. According to this: https://core.trac.wordpress.org/browser/tags/4.7.3/src/wp-includes/functions.php#L325 - Wordpress uses standard PHP serialization functions, so looks like something corrupted Yours.

Answer 3

It doesn't look like valid JSON. It's actually serialized array: ["xyz",""]
a is for array,
2 indicates elements count
s is string
3 string length
"xyz" string 'content'
s - string
0 - string length
"" string 'content'
