Not all fonts will be in 1 location - Adobe fonts is a collection of font libraries.
Corbel is a free font - https://www.dafontfree.io/corbel-font/
As is Constantia - https://www.dafontfree.io/constantia-font/
As a designer, you'll need to be able to research and find things by yourself, including fonts, images, design styles.
It won't be all on a plate for you.
Important note on Fonts - they are software - they will have a EULA (end user License agreement)
Where some fonts can be free, they are not always free to use for commercial work, and you may have to pay for them for commercial use.
Free fonts can also have issues around Embedding, as they would require you to purchase the full version to allow the embedding.
Always check the EULA to ensure that the fonts you are using are fit for purpose.
Same goes for images or anything else you are using in your designs.
