There are quite a lot of tutorials in the official documentation. Most of these are pdf files you can find in the Documentation directory inside your CC3+ data directory.
A significant portion of the CC3+ program manual are tutorials for how to do things in CC3+, these tutorials mostly use overland mapping as an example, but they do teach you a lot of useful things even if you will primarily be doing other kinds of maps, like dungeons.
Almost all the products/add-ons comes with an Essentials guide which gives you a brief quick start into that product with a short introductory tutorial.
The annuals are not just a great source of new styles and symbols, but each individual issue comes with a mapping guide for that style. Even if you don't plan to use that style, these guides often end up teaching you additional tips and tricks useful for your other mapping.
The Tome of Ultimate Mapping contains various tutorials for almost every one of ProFantasy's products. Just as with the user manual, tutorials may still be helpful even if they are for a different type of map since the basic way of doing things in CC3+ doesn't change between overland and dungeon and city maps.
The ProFantasy Blog contains a lot of useful articles, many of which take a tutorial format.
