I guess that depends on what you do. I've never felt that I do not have enough ecosystem in Delphi/FreePascal but I know there are areas where I would not be lucky if I ever went there. Then again on few occasions I had no problems creating pascal headers from C libraries I wanted to use. There are tools that depending on particulars can make it almost automatic.

Python4Delphi project has been around for around twenty years now, allows using Python from within a Delphi/Lazarus GUI framework: https://github.com/pyscripter/python4delphi

Not saying pascal is perfect but I haven't come across any issues with missing libraries.
