The thinkpads (at least the X,T and P models) tend to be a different story but even that is changing in recent years
I get that shit happens and sometimes products have defects. I'm willing to put up with a reasonable amount of annoyance. I'll never buy another Lenovo product, though, because once you're out of warranty, you may as well throw the thing away. They don't care at all.
Maybe relative to Thinkpads of yesteryear, but in comparison to the field of professional laptops, they are still best in class.
While it has amazing components like the AMD Ryzen, Radeon GPU, etc. The quality of the rest of the components is trash.
The trackpad keeps disconnecting, the screen is very poorly backlit, the speakers sound like headphones that came with 1990 Walkmans. It's not a good laptop even if it looks good on paper.
I don't know those answers; perhaps carbon plastic wins on all metrics. It would be interesting to learn.
Usually tensile strength. For example: Tensile strength: even a commodity PA6-GF30 (most half-decent tools are made of) is ~110MPa [according to ISO 527], cast Aluminum - would be ~150MPa (22K psi for the imperial folks) depending on the alloy.
Of course, most laptops would be using an ABS blend, which is the hallmark low-quality tools.

That would depend on the top finish, not so much of the material itself.

Would it? If I dropped an aluminium bodied laptop like a Macbook or HP Envy, I'd expect it might scuff and slightly dent at the point of impact. If I dropped the cheapest plastic bodied thing from Currys/Walmart/whatever, I'd expect it might scuff and crack the plastic between screws or something.
What top finish would you apply to a cheap plastic laptop to make it 'ding' like aluminium instead of crack in a drop test?
Again, a good plastic with glass or carbon fiber reinforcement would have similar properties to al-mg body, yet feel cheap as most people consider all plastics quite the same. For example: polycarbonate, 30% carbon fiber would have tensile strength of 150MPa (which the same to cast aluminum)
You said above that that was more to do with 'top finish' than 'material'; that's what I was responding to - how would you finish crackable plastic material to make it dent like aluminium/alloy instead.
As someone else noted, "strength" in material is not one-dimensional. Carbon plastic is still way more conducive to cracking, for one.
Ergo, there is no "objectively better" choice between metal/plastic/carbon in the general case, it comes down to preferences, priorities and requirements.
The issue seems to be less with structural design and particular choice of plastics that cause them to not hold up to wear.
If only it had a less brittle video-out and TB it would be close to perfect even today, but these to otherwise minor factors unfortunately make it close to useless apart from as a spare travel device.
