Handle is too big? That's not a thing. Nobody ever in the history of soldering has had problems with the handle being too big. Your hands are bigger than the handle in any case, but you're not putting the handle down into your work. The soldering tip is what matters, and there are a wide variety of soldering tips available for the FX-888D that will suit any job.
The FX-888D is a great soldering station for both beginners and advanced users. They have better models, but those also cost more.
Notably, the FX-951 has the heater embedded in the soldering tip, this makes the tip heat up faster, makes the temperature more accurate, and makes it stay at that temperature better, even when soldering large components or ground planes that suck a lot of heat away. Making the FX-951 a better model, if you can afford it.
I didn't know about any of this when I bought the FX-888D, or I might've gone with the FX-951, but I don't regret my purchase. It has handled anything I threw at it with ease.
Edit: As for the tips to get. Some chisel tips and bevel tips in different sizes depending on what kind of work you are planning to do should have you sorted. Some people really like the bent conical tips, I don't have one so I have no opinions on them. Chisel tips and bevel tips have been plenty enough for me. The bevel tips are very useful for drag soldering SMD chips with many legs quickly, the chisel tips are more general use, but both can be used for general use.
