There's some books by Nick Hodges (former delphi product manager)
'Coding in Delphi' and 'More coding in delphi' for more advanced stuff
The negatives with delphi are its been poorly marketed for years, and it costs money to use, though the community edition is available now. Object pascal is a bit dated imho, but what makes Delphi powerful is the components, there's 2 the VCL which is the original in windows only, then fire monkey which is the new cross platform one.
If you want to see components have a look at tmssoftware.com for some drag and drop components, you can even make web applications with Delphi with their web components (they cross compile to javascript)
Here's some resources to get you started
There's a free book here: https://lp.embarcadero.com/Object-Pascal-Handbook-2021
and another here (pdf) (probably the best to start) https://www.marcocantu.com/edelphi/EssentialDelphi_1033_2020...
There's intro videos here https://www.embarcadero.com/resources/videos
They have a YouTube channel here, that has a lot of more in depth stuff https://www.youtube.com/c/EmbarcaderoTechnologies
