If you break down this question tribology-style. First, the fundamentals: Wear protection comes from two main regimes. Hydrodynamic lubrication(full film, parts separated by oil pressure) is driven mostly by viscosity under heat and shear— that’s your HTHS number. Boundary lubrication (metal...

For your 2022 3.5EB F-150 with easy daily/vacation driving (no towing/hard use) and ~42k miles, any full OTS synthetic 5W-30 is fine. All three of your options do that, so you really can’t go wrong—they’re all excellent and will give great protection with reasonable OCIs (say 5-7k miles to play...

Yes, the L3B (2.7L turbo) and LSY (2.0L turbo) can be considered harder on oil than many NA engines, mainly due to being turbocharged GDI designs. The direct injection increases risks of fuel dilution and LSPI, while the turbo exposes oil to much higher temperatures (especially at the bearings)...
