I am a millennial and just a month back made an internal tool with Lazarus/FPC for a Fortune 500 company.
This is very interesting to know. Although there is an obvious query: is your the language choice, or a company choice? how much projects that company decide to do with FPC/Delphi?
Because in a big company many developers do they private tools, in whatever language they want. But it's very different, of course, what "official" language a company choose to use in enterprise projects.
If you want a RAD tool that's not Microsoft and you don't want to do C++, you have no option my friend Lazarus/Delphi is all there is. And while RAD is great n all, you can do as low level stuff as you want...
Yes and no. Today many interactive apps are web based. Not only internet/intranet, but also local apps, as VS Code.
So, if RAD is related to Gui, one has many choice (although I think web base local apps are greatly inefficient).
