Dan,
Appreciate the feedback, and actually I rather agree. More damage is done by striping an engine than leaving it alone, oiled, bagged up, de-humidified and ready!

However, in principle I'm looking to better understand should I need to strip and clean it (metal shielded front bearing, dirty track, a little insurance of cleanliness), what would be a good process and material?

Agreed, crankshaft, rod, piston, sleeve and head left well alone, and maybe rebuilt lightly oiled etc. However when I used to race back in the day I always did an ARO routine (3in1 actually!) and my engines were notably more reliable than most. I understand now however as materials have changed best to use oils designed for purpose (really hence this post), but I'm a believer in ARO.

So thoughts on cleaning bearings and lubing? WD40 ok for both the ceramic and metal, then just relube with ARO, or is there something better? Nitro fuel is more a wash, I feel a little blast is required.
