I've created small projects in Lazarus and you are right in all points except in the small binary part, also I would add that it comes with db drivers for Postgrees, MySQL and Firebird SQL out of the box.
If you compare to the "modern" way of building cross-platform apps: Electron ... with its 100s of MBs, I'm definitely regarding Lazarus binaries as small :)
Depends on what you define as small but if you remove the GDB debugging information you can trim down your binaries by a huge amount. My last project was 3.4MB.
