Answer 1

Your first con is also a pro. If you replicate shared code in each dll the dlls get bigger and bigger. Even when using dlls you can prevent this by moving shared code in a separate dll.

Pros:

1. Types are shared. No TFont is not a TFont problem
2. Memory manager is shared. Strings and classes can be used as parameter between plugins without problems.

Cons:

1. Plugins can be built using Delphi or BCB only.
2. Plugins should use the same Delphi or BCB version.

Have you considerd using COM? COM makes it possible to share types, strings and classes and the plugins can be written in many programming languages.
