On the first one I'll go for Nxc4
Your beliefs create your reality, so be careful what you wish for.

Rf3, Nxc4, Qh3, Nf6, there is not much difference between these movements, slight advantage for black, it would be good to see top engines analyzing an hour or more to see if Rf3 can be decisive. DanaSah likes Rf3 after 12 minutes.

I don't know about that, I thought Rf3 was clearly better.

Rf3 Nd5 Qg4+ leaving black with probably +1
Rf3 Qd2 Rc5, also a nice advantage.
