Yes, that’s annoying both during writing and later, when you want to e.g. join some paragraphs together or change font for the whole article.

Paragraphs can be joined together by going to the beginning of a paragraph and pressing backspace. In just the same way you would do it in a text editor.

Changing "fonts" is not something that WordPress itself has support for. Presumably a plugin or something would add that, offering a selection of fonts from Google Fonts or the like. Nevertheless, adding font choice would be something that would be added to these blocks by said plugin.

The "whole article" thing I grant you is unfinished. There is the ability to select multiple blocks, but the interface to adjust the specific details of those multiple blocks is still in the "Coming Soon" phase. I also have issues with the lack of good block-nesting in the interface. The code supports it, but there's no blocks to implement it yet, and this makes styling somewhat difficult. Hopefully that gets finalized fairly soon.
