Creating Formatted Information Boxes?

Is there a way I can use WordPress to keep consistent formatting of my information? For example, I have a bunch of names and contact information scattered throughout my website’s content. I would like it so that the name is always in bold, their title in italic, their phone number uses only the extension unless it’s outside the building, then displays the entire number, etc.

I can go through the site and change these, but I want everyone who edits the content to follow these same strict standards. I would like to do it with more than just names, too, but also places, hour lists, and other information we’ll put frequently throughout our pages.

Is there a better way to do this, so that we will ALWAYS force title case for people’s titles, and it will ALWAYS be italic, and there will ALWAYS be a phone number’s extension shown unless it’s a different number from the building’s?

I am thinking there could be like an information box with set fields I can fill in each time I want to put information somewhere (like this is a box for a contact, and this is a box for an address, and this is a box for a warning message, etc.) and it will format automatically. I’ve been in this place when using WordPress multiple times so I’m thinking there must be a practical solution here. And this way later on if we want to change the rules for formatting, we can just change the box’s instructions.

Thanks,
M
