Well this is how I am doing things right now. I've been doing recording for about 3 years now. Ever since my youngest boy finished his baseball carreer and now I have a lot more spare time.

Vocal input:
XML 770 condenser microphone, no pop filter, (I don’t like it blocking my view) to Scarlet 2i2 Audio Interface.

Vocal track chain in Reaper DAW
Input FX: ReaGate. Set around -60db. To reduce noise from my computer and room.

Subtractive EQ, compressor, Additive EQ, compressor, W.A. Productions Vocal Limiter
I read that is was better to do the compression and eq this way. Not sure if I can tell the difference!

Vocal Reverb: ReaVerbate (set like Kenny G showed in his recent Reverb video)
Vocal Delay: ReaDelay (set like Kenny G showed in his recent Delay video)

Edit split at the breaths and reduce.
On the harmony tracks, edit split and delete all breaths.
Nudge harmony tracks if required to line up better to main vocal.

And yes I must say that I stole Mr. Floyd's vocal technique (from your pinned video, a little bit of me goes a long long way)
Singing to the side of the microphone. Seems to have reduced my sibilance too
