Yes, all of them have 128 bit wide flash that allows zero waitstate
execution at the maximum CPU clock.

Not bad, I ordered a couple books on ARM off Amazon, may get into it finally.
From what I see they are same price as AVR mega, low power and much faster.
And NXP is very generous with samples.

I'd use the ATmega1281 as the ATmega128 is a bit old hat now (plus the
ATmega1281 can run a little faster at 3.3V as it has a voltage vs. speed
rating which the ATmega128 doesn't). If you want something a little smaller
the ATtiny48 and ATtiny88 are nice chips. I'm quite a fan of the AVRs
personally...

The books on ARM may be too generic. Most of the things you need to
know are in the user manual and the datasheet. NXP's Cortex based
LPC1000 series need no assembly at all to get running. Even interrupt
routines do not need special care.

While at least some memory chips are outsourced, the AVRs are still
manufactured inside Atmel.

I get leadtime guides from distributors and many semiconductor
companies have 20+ weeks leadtime right now.

Talked to one large customer who got 42 weeks lead time for mobile DDRs.

When lead times go up, some customers tend to order components
from several suppliers, so apparent demand is higher than real demand,
so anything in stock is swallowed up immediately.

If there is no stock, then it normally takes 16 weeks to
produce new things for any semiconductor manufacturer.

Quite often, the fab capacity is not the problem, but testing is.
If you can't buy new testers, then capacity cannot increase.
Companies doing test equipment cant deliver, because they
have long lead times on components. Hmmm...
