OK, then I suggest using Text Snippets, which allows you type key phrases, and then expand them.
It’s also possible as suggested in the next reply (of that previous link) to use Templater and have that present various texts to your liking as templates.
And even Quick Add can be used for stuff like this. The advantage with this one is that it could present you with various grouping options to select phrases/text.
So not sure which one would suit you best, as it depends heavily on your use case, and the number of text you want accessible through this system and so on.
But for fair amount of different text alternatives, if you’re able to give them a proper key phrase, I think the Text Snippets could be a viable option.
