Can of worms, but I'll bite.
Fully synth will not harm your engine, or clutch in any way. It will cost more - some 30 % more than semi synth.
Benefits are better cold start protection, less gum and dirt formations inside the engine and even some minimal fuel savings (up to 1%, but at 10.000 km change interval it will cover the price difference between semi and full synth). I put full synth in all the vehicles I (and some friends) use. Old seals that are due for a change could show leaking. That has been the only "downside" by now.
Most things done in a hurry need to be done again - patiently.
