Thanks for reaching out.
They are V2 elements, could be advanced but not really as it's only the second version of the classic one. Just like other software, it may replace the classic ones in the future though, that's just my opinion as that's I usually see evolving features. It may or may not happen. And the good part of it is you have multiple options, use an element that directly uses global configuration or use v2 elements that you wish to have specific or local configuration.
The v2 elements have more options and features than the classic one thus resulting to the more complex structure and more advanced controls. And V2 elements has its own setting which may or may not follow the global settings, the global settings usually serve as the default settings where v2 element can inherit, like if you set the v2 element's font to inherit. V2 element best works with preset, as you can save a default preset and it will act as a global configuration for that same v2 element type. Please check this https://theme.co/apex/forum/t/how-to-use-presets/14850/8, https://theme.co/apex/forum/t/template-manager-discussion/12191, then you can set default preset in Templates > Cog Icon > Template Manager
